I'm Josh, and there's 16 00:00:50,200 --> 00:00:52,720 Speaker 1: Chuck and Jerry's here too. You can't see her, but 17 00:00:52,760 --> 00:00:56,840 Speaker 1: you can if you relax your eyes lose focus, she 18 00:00:56,960 --> 00:01:00,120 Speaker 1: may just pop right out at you and be like, hey, 19 00:01:00,120 --> 00:01:00,680 Speaker 1: I'm Jerry. 20 00:01:00,720 --> 00:01:04,560 Speaker 2: Could meet youa you thought I wasn't real? All you 21 00:01:04,640 --> 00:01:05,959 Speaker 2: need her lazy eyes. 22 00:01:06,360 --> 00:01:09,240 Speaker 1: That's well, no, actually it doesn't work if you have 23 00:01:09,440 --> 00:01:10,160 Speaker 1: lazy eye. 24 00:01:10,360 --> 00:01:11,640 Speaker 2: I know that's the opposite. 25 00:01:12,200 --> 00:01:13,119 Speaker 1: We'll get to that later. 26 00:01:13,120 --> 00:01:15,160 Speaker 2: I would love to see Jerry in in a Magic 27 00:01:15,200 --> 00:01:17,319 Speaker 2: I poster popping out in my room. 28 00:01:18,160 --> 00:01:20,839 Speaker 1: All right. You know, well, you know, it's actually become 29 00:01:20,959 --> 00:01:23,440 Speaker 1: so easy to do. There's so many programs out there 30 00:01:23,480 --> 00:01:24,920 Speaker 1: now that you do it. 31 00:01:25,000 --> 00:01:25,240 Speaker 2: Huh. 32 00:01:25,280 --> 00:01:28,160 Speaker 1: You could at the very least a more capable and 33 00:01:28,200 --> 00:01:30,520 Speaker 1: skilled stuff you should know, listener, probably could. 34 00:01:30,959 --> 00:01:32,280 Speaker 2: I'll just keep talking about it. 35 00:01:32,440 --> 00:01:32,800 Speaker 1: There you go. 36 00:01:33,920 --> 00:01:34,880 Speaker 2: That's what we're talking about. 37 00:01:34,880 --> 00:01:35,039 Speaker 3: Though. 38 00:01:35,080 --> 00:01:38,840 Speaker 2: If you are a person of a certain age, and 39 00:01:38,920 --> 00:01:42,560 Speaker 2: you were either like a teenager or up probably in 40 00:01:42,560 --> 00:01:46,560 Speaker 2: the nineteen nineties early nineteen nineties, yep, then you probably, 41 00:01:46,880 --> 00:01:50,720 Speaker 2: at some point, much like Ethan Suppley in the movie 42 00:01:50,760 --> 00:01:55,120 Speaker 2: Mall Rats, would stand somewhere in a shopping mall at 43 00:01:55,120 --> 00:01:58,240 Speaker 2: a wooden kiosk, staring at a poster, waiting for that 44 00:01:58,880 --> 00:02:01,360 Speaker 2: shark or that sale to come out from the background 45 00:02:01,360 --> 00:02:04,360 Speaker 2: of that poster. Yeah, the hidden, the hidden trick. 46 00:02:04,960 --> 00:02:08,160 Speaker 1: I tried it so many times, and I think maybe 47 00:02:08,480 --> 00:02:11,720 Speaker 1: one out of fifty I was able. Oh yeah, I 48 00:02:11,800 --> 00:02:13,680 Speaker 1: was not good at it, but I have to say Chuck. 49 00:02:14,000 --> 00:02:18,240 Speaker 1: After researching it yesterday and today, my eye muscles have 50 00:02:18,400 --> 00:02:20,360 Speaker 1: never been in better shape than they are right now. 51 00:02:20,639 --> 00:02:22,040 Speaker 2: Did you try looking at them again? 52 00:02:22,200 --> 00:02:24,560 Speaker 1: Yes, I've been popping and locking and like just I'll 53 00:02:24,600 --> 00:02:26,639 Speaker 1: be like here, give it to me, bam, I'll see 54 00:02:26,639 --> 00:02:28,000 Speaker 1: that one. Oh, let's see another one. 55 00:02:28,440 --> 00:02:30,760 Speaker 2: Actually, I've got it, Yes, I did. 56 00:02:31,360 --> 00:02:34,040 Speaker 1: I finally relax. I guess is what it comes down to. 57 00:02:34,639 --> 00:02:39,240 Speaker 1: But I've gotten to the point where I can, once 58 00:02:39,280 --> 00:02:41,920 Speaker 1: I see it, I don't have to keep that focus. 59 00:02:41,960 --> 00:02:46,760 Speaker 1: I can actually look around inside the picture from like 60 00:02:46,800 --> 00:02:47,919 Speaker 1: different angles and stuff. 61 00:02:47,960 --> 00:02:51,119 Speaker 2: It's really cool. Yeah. I got to that point too, 62 00:02:52,320 --> 00:02:54,200 Speaker 2: to where like at first I would do the trick 63 00:02:54,240 --> 00:02:56,880 Speaker 2: where you like in the book version, where you would 64 00:02:56,880 --> 00:02:59,239 Speaker 2: hold it very close to your face and slowly back 65 00:02:59,280 --> 00:03:02,240 Speaker 2: it away, because as we'll see, that's one technique to 66 00:03:02,280 --> 00:03:05,000 Speaker 2: see what the hidden picture. But then I got to 67 00:03:05,040 --> 00:03:07,680 Speaker 2: where once you once you sort of contrain yourself, then 68 00:03:07,720 --> 00:03:09,400 Speaker 2: you can just sort of look at it like you said, 69 00:03:09,440 --> 00:03:11,960 Speaker 2: and you know, the little trick with your eyes, and 70 00:03:12,000 --> 00:03:14,160 Speaker 2: then there's that polar bear or whatever. 71 00:03:14,400 --> 00:03:17,040 Speaker 1: Yeah, but I should say it's been it's been brought 72 00:03:17,080 --> 00:03:19,560 Speaker 1: to our attention. I guess ever since the Millie Vanilli 73 00:03:19,639 --> 00:03:23,040 Speaker 1: episode that even like that kind of definition is not 74 00:03:23,160 --> 00:03:26,880 Speaker 1: necessarily enough for some of our listeners. So I feel like, no, 75 00:03:27,000 --> 00:03:28,680 Speaker 1: I think we should go a little further. If you've 76 00:03:28,720 --> 00:03:32,800 Speaker 1: never seen a magic eye poster or you know generically 77 00:03:32,800 --> 00:03:38,480 Speaker 1: called the stereogram, what we're talking about is a a strange, 78 00:03:38,640 --> 00:03:45,200 Speaker 1: seemingly random pattern of different colors almost splattered across a poster, 79 00:03:46,080 --> 00:03:49,720 Speaker 1: and that if you relax your eyes is a certain 80 00:03:49,760 --> 00:03:53,040 Speaker 1: way so that you focus as if you're looking beyond. 81 00:03:52,720 --> 00:03:54,680 Speaker 2: The poster, like right through it. Yeah. 82 00:03:54,760 --> 00:03:59,280 Speaker 1: Hm, in some sort of magic scientific way that will explain, 83 00:03:59,600 --> 00:04:03,400 Speaker 1: sort of a three dimensional image suddenly forms. You suddenly 84 00:04:03,480 --> 00:04:06,200 Speaker 1: see a three D image that you cannot see if 85 00:04:06,240 --> 00:04:09,360 Speaker 1: you're if you're not looking at it the right way. Yeah, 86 00:04:09,400 --> 00:04:12,680 Speaker 1: when you do see it, there's it's almost inevitable you're 87 00:04:12,680 --> 00:04:16,880 Speaker 1: gonna say wow, oh, gosh or something like that. It's 88 00:04:16,960 --> 00:04:19,160 Speaker 1: thrilling every single time it is. 89 00:04:19,240 --> 00:04:21,640 Speaker 2: It appears to kind of jump away from the rest 90 00:04:21,640 --> 00:04:25,800 Speaker 2: of the image. But nice definition. But I think we 91 00:04:25,800 --> 00:04:29,120 Speaker 2: should go back because there's kind of a long and 92 00:04:29,200 --> 00:04:32,120 Speaker 2: winding road to how we eventually got to the early 93 00:04:32,200 --> 00:04:36,800 Speaker 2: nineteen nineties with these magic eye posters. That were you know, 94 00:04:36,839 --> 00:04:38,599 Speaker 2: they were real fad and we'll get to that. You know, 95 00:04:38,640 --> 00:04:40,640 Speaker 2: they sold a lot of those things in a short 96 00:04:40,680 --> 00:04:43,640 Speaker 2: amount of time. But it goes all the way back 97 00:04:43,760 --> 00:04:48,640 Speaker 2: to the early scientists of the world trying to figure 98 00:04:48,680 --> 00:04:52,200 Speaker 2: out how in the world when you have two eyeballs 99 00:04:52,880 --> 00:04:57,760 Speaker 2: that are spaced about sixty something millimeters apart. You know, 100 00:04:57,800 --> 00:04:59,880 Speaker 2: if they're spaced apart, they're gonna be seeing things f 101 00:05:00,000 --> 00:05:02,320 Speaker 2: from a slightly different perspective. And how in the world 102 00:05:02,400 --> 00:05:04,320 Speaker 2: do we do that and come up with like a 103 00:05:04,440 --> 00:05:06,679 Speaker 2: solid focus on things? 104 00:05:07,000 --> 00:05:10,000 Speaker 1: Yeah, I mean I had never really thought about it before, 105 00:05:10,040 --> 00:05:12,839 Speaker 1: but binocular vision is what you're talking about. And yeah, 106 00:05:12,880 --> 00:05:14,960 Speaker 1: by rights, we have two eyes, and like you said, 107 00:05:14,960 --> 00:05:17,360 Speaker 1: they're separated by a certain amount of distance, So why 108 00:05:17,360 --> 00:05:19,600 Speaker 1: don't we see two images of. 109 00:05:19,520 --> 00:05:22,800 Speaker 2: The world, Yeah, very lightly from one another. Right. 110 00:05:23,640 --> 00:05:25,760 Speaker 1: What It turns out that if we did do that, 111 00:05:25,960 --> 00:05:29,360 Speaker 1: we probably wouldn't be able to see with depth perception. 112 00:05:29,520 --> 00:05:33,679 Speaker 1: It's very crazy kind of It's called stereopsis is another 113 00:05:33,680 --> 00:05:37,960 Speaker 1: word for depth perception, and it is in combining those 114 00:05:38,080 --> 00:05:41,440 Speaker 1: two images that each eye gives the brain that we're 115 00:05:41,480 --> 00:05:44,520 Speaker 1: able to see in one complete picture that has depth 116 00:05:44,800 --> 00:05:49,760 Speaker 1: and richness and uh, maybe even a little kindness depending 117 00:05:49,800 --> 00:05:50,680 Speaker 1: on what you're looking at. 118 00:05:51,240 --> 00:05:54,720 Speaker 2: Yeah, and the brain does this immediately. It figures it 119 00:05:54,760 --> 00:05:57,240 Speaker 2: out so fast you don't even know what's happening. But 120 00:05:57,320 --> 00:05:59,640 Speaker 2: we can go all the way back to our friend Ptolemy, 121 00:05:59,720 --> 00:06:03,800 Speaker 2: who talked about quite a bit. Yeah, second century Roman astronomer. 122 00:06:04,320 --> 00:06:06,520 Speaker 2: And this is one of sort of the early ideas 123 00:06:06,520 --> 00:06:09,880 Speaker 2: that were was put forward. And you know, they, as 124 00:06:10,040 --> 00:06:12,240 Speaker 2: as with all things sort of science, they put forward 125 00:06:12,279 --> 00:06:14,840 Speaker 2: some ideas that aren't quite right and they're refined over 126 00:06:14,839 --> 00:06:16,880 Speaker 2: the years until they get to the reality of it. 127 00:06:17,120 --> 00:06:18,599 Speaker 1: This is an ain't quite right one. 128 00:06:18,800 --> 00:06:21,160 Speaker 2: Yeah, ain't quite right because told me he thought that 129 00:06:21,240 --> 00:06:25,240 Speaker 2: your eyes sent out raise basically visual rays that hid 130 00:06:25,279 --> 00:06:29,800 Speaker 2: an object, and when we're seeing something in focus, that 131 00:06:29,880 --> 00:06:32,360 Speaker 2: means it's even it's kind of hard to explain how 132 00:06:32,360 --> 00:06:36,520 Speaker 2: bad it is that the eyeball rays will converge on 133 00:06:36,640 --> 00:06:39,240 Speaker 2: an object. And when they converge on that object, that's 134 00:06:39,279 --> 00:06:42,760 Speaker 2: when you can see something in focus, basically, and if. 135 00:06:42,720 --> 00:06:44,880 Speaker 1: They converge in it too much, they burn it to 136 00:06:44,960 --> 00:06:48,960 Speaker 1: a cinder. Excellently, he had it, he picked up there's 137 00:06:48,960 --> 00:06:52,320 Speaker 1: two things. He had it backwards. We're actually accepting rays 138 00:06:52,680 --> 00:06:55,640 Speaker 1: rather than shooting him out, so he's kind of getting there. 139 00:06:56,400 --> 00:06:59,960 Speaker 1: And then he noticed that our two eyes create an 140 00:07:00,800 --> 00:07:04,800 Speaker 1: that's our focus. It can be wide narrow, depending on 141 00:07:04,839 --> 00:07:07,919 Speaker 1: what we're looking at. If it's far away, the focus 142 00:07:08,000 --> 00:07:11,520 Speaker 1: is going to be at a sharper angle. If it's closer, 143 00:07:11,520 --> 00:07:14,440 Speaker 1: it's going to be at a wider angle. And he 144 00:07:14,560 --> 00:07:16,840 Speaker 1: was onto something, but he didn't. He who wasn't able 145 00:07:16,840 --> 00:07:18,440 Speaker 1: to really put two and two together, and then he 146 00:07:18,480 --> 00:07:19,600 Speaker 1: died and that was it for him. 147 00:07:19,960 --> 00:07:23,120 Speaker 2: Yeah, that's right. So up next, I guess we can 148 00:07:23,160 --> 00:07:28,160 Speaker 2: flash forward to this Arab scholar name all has In 149 00:07:28,360 --> 00:07:29,120 Speaker 2: is what I'm going to say. 150 00:07:29,160 --> 00:07:30,880 Speaker 1: I think that's great, right. 151 00:07:32,040 --> 00:07:35,320 Speaker 2: And he basically said, all right, what we have is 152 00:07:35,360 --> 00:07:39,240 Speaker 2: an ability to sense this convergence of our eyes when 153 00:07:39,240 --> 00:07:43,400 Speaker 2: they focus on an object. And what this is called basically, 154 00:07:43,560 --> 00:07:45,200 Speaker 2: I don't know if he even said the word depth, 155 00:07:45,440 --> 00:07:47,680 Speaker 2: but it helps us figure out how far something is, 156 00:07:47,840 --> 00:07:48,560 Speaker 2: which is depth. 157 00:07:49,040 --> 00:07:51,800 Speaker 1: Yes, And so his idea was that we could we 158 00:07:51,880 --> 00:07:55,000 Speaker 1: had some sort of sense that we was so involuntary 159 00:07:55,040 --> 00:07:56,640 Speaker 1: we weren't even aware of it, and that's how we 160 00:07:56,680 --> 00:08:00,160 Speaker 1: knew its true. Yeah, for sure, but still not quite right. 161 00:08:00,200 --> 00:08:04,360 Speaker 1: There about six hundred years later, Kepler and Descartes kind 162 00:08:04,360 --> 00:08:07,080 Speaker 1: of picked up on something similar, and they said, rather 163 00:08:07,160 --> 00:08:11,360 Speaker 1: than being able to sense the degree of convergence that 164 00:08:11,400 --> 00:08:15,680 Speaker 1: our eyes are focusing, we actually can feel how our 165 00:08:15,720 --> 00:08:19,040 Speaker 1: eyes are rotating at any given point, and that's how 166 00:08:19,080 --> 00:08:22,560 Speaker 1: we know where our eyes are focused or not focused. 167 00:08:22,800 --> 00:08:27,040 Speaker 2: Yeah, Descartes said, like googly eyes, you know exactly. 168 00:08:26,960 --> 00:08:30,320 Speaker 1: And so like it was just wrong, wrong, wrong. Finally, 169 00:08:30,880 --> 00:08:35,080 Speaker 1: in the eighteen thirties, an Englishman stepped up. His name 170 00:08:35,120 --> 00:08:39,360 Speaker 1: was Sir Charles Wheatstone. Yeah, and he said, I've got this. 171 00:08:39,440 --> 00:08:43,760 Speaker 1: Everybody check this out. I have invented an invention that 172 00:08:43,880 --> 00:08:48,280 Speaker 1: will prove that my hypothesis of binocular vision providing us 173 00:08:48,440 --> 00:08:54,080 Speaker 1: one single image with depth is actually from well take 174 00:08:54,080 --> 00:08:54,480 Speaker 1: a chuck. 175 00:08:56,880 --> 00:08:59,280 Speaker 2: Well, you know what's funny is in my notes I had. 176 00:08:59,400 --> 00:09:03,520 Speaker 2: Wheatstone says, quote, I got this nice exactly what you said. 177 00:09:03,520 --> 00:09:04,400 Speaker 1: It's simpatico. 178 00:09:04,760 --> 00:09:05,840 Speaker 2: What were you setting me up for? 179 00:09:06,760 --> 00:09:07,240 Speaker 1: I don't know. 180 00:09:08,240 --> 00:09:10,320 Speaker 2: Well, he had an invention. Can I just describe that 181 00:09:10,400 --> 00:09:11,080 Speaker 2: at least? Yeah? 182 00:09:11,080 --> 00:09:12,000 Speaker 1: The stereoscope. 183 00:09:12,120 --> 00:09:16,000 Speaker 2: Yeah, the stereoscope sat. The first version of this that 184 00:09:16,080 --> 00:09:19,520 Speaker 2: he introduced sat on a table. There's a great picture. 185 00:09:19,600 --> 00:09:22,240 Speaker 2: It turns out that Brian May of Queen is a 186 00:09:22,240 --> 00:09:29,000 Speaker 2: big wheatstone slash three D stereogram binocular vision enthusiast, and 187 00:09:29,120 --> 00:09:31,400 Speaker 2: so there's some cool pictures of him looking at this 188 00:09:31,559 --> 00:09:35,120 Speaker 2: through this original stereoscope. So it sits on a desk 189 00:09:35,800 --> 00:09:39,320 Speaker 2: and in the center you put your eyes up to 190 00:09:39,640 --> 00:09:42,000 Speaker 2: you know, what looks like a little viewmaster or a 191 00:09:42,080 --> 00:09:46,240 Speaker 2: VR headset basically, and it has these two angled mirrors, 192 00:09:46,240 --> 00:09:48,839 Speaker 2: one for each eye. So when you look through it, 193 00:09:48,840 --> 00:09:51,439 Speaker 2: it angles one eye out to the right and one 194 00:09:51,440 --> 00:09:54,800 Speaker 2: eye out to the left, and in that peripheral vision 195 00:09:55,240 --> 00:09:58,440 Speaker 2: on each side there's a little small wooden wall with 196 00:09:58,520 --> 00:10:01,480 Speaker 2: a picture on each one. So one eye is looking 197 00:10:01,480 --> 00:10:03,839 Speaker 2: at the left picture, the right eye is looking at 198 00:10:03,840 --> 00:10:06,520 Speaker 2: the right picture, and you you know, it has two 199 00:10:06,520 --> 00:10:09,800 Speaker 2: little thumbholes that you hold. It's very elegantly a little 200 00:10:09,800 --> 00:10:10,880 Speaker 2: steampunk looking thing. 201 00:10:11,000 --> 00:10:11,800 Speaker 1: It definitely is. 202 00:10:12,120 --> 00:10:17,079 Speaker 2: And that was how he basically proved this, by having 203 00:10:17,120 --> 00:10:22,320 Speaker 2: each eye look at two separate things, but they're both flat, flat, 204 00:10:22,640 --> 00:10:24,720 Speaker 2: flat images of the same thing. Basically. 205 00:10:24,760 --> 00:10:25,760 Speaker 1: That's really that's key. 206 00:10:25,880 --> 00:10:26,040 Speaker 2: Right. 207 00:10:26,080 --> 00:10:28,960 Speaker 1: So let's say you had an image of an apple cart. 208 00:10:29,559 --> 00:10:31,880 Speaker 1: You have two pictures of that apple cart, and your 209 00:10:31,920 --> 00:10:35,000 Speaker 1: eyes are seeing each one right, because there's that barrier 210 00:10:35,040 --> 00:10:38,160 Speaker 1: in between your two eyes, so your eye is just 211 00:10:38,200 --> 00:10:40,760 Speaker 1: seeing the left image, your right eye seeing just the 212 00:10:40,840 --> 00:10:41,400 Speaker 1: right image. 213 00:10:41,480 --> 00:10:42,160 Speaker 2: Right. Yes. 214 00:10:42,320 --> 00:10:44,960 Speaker 1: The distinction here, Chuck, and this is where Wheatstone like 215 00:10:45,040 --> 00:10:49,079 Speaker 1: really laid the foundation for understanding binocular vision is that 216 00:10:49,240 --> 00:10:52,760 Speaker 1: each of those pictures has to be slightly different in perspective. 217 00:10:53,040 --> 00:10:53,440 Speaker 2: That's right. 218 00:10:53,760 --> 00:10:57,320 Speaker 1: So either there's a slightly different angle, or you took 219 00:10:57,360 --> 00:10:59,320 Speaker 1: one picture and then moved a foot to the left 220 00:10:59,320 --> 00:11:01,320 Speaker 1: and took the other picture, and those are what you're seeing. 221 00:11:01,760 --> 00:11:05,400 Speaker 1: And what he showed is that the brain can sense 222 00:11:05,200 --> 00:11:09,560 Speaker 1: those slight, slight differences in perspective and that's what it 223 00:11:09,720 --> 00:11:13,480 Speaker 1: uses when it combines two images into one image in 224 00:11:13,520 --> 00:11:16,240 Speaker 1: your field of view to give it depth. That's how 225 00:11:16,240 --> 00:11:21,600 Speaker 1: it senses depth, those differences in perspective or angle that 226 00:11:21,720 --> 00:11:24,359 Speaker 1: each eye is feeding the brain as an image. 227 00:11:24,640 --> 00:11:27,200 Speaker 2: Yeah. And if you're thinking this sounds like the little 228 00:11:27,280 --> 00:11:29,560 Speaker 2: viewmaster that you had when you were a kid, that's 229 00:11:29,600 --> 00:11:31,360 Speaker 2: exactly what it is, same exact thing. 230 00:11:31,800 --> 00:11:34,400 Speaker 1: Yeah, And the same way that like the computer went 231 00:11:34,440 --> 00:11:37,360 Speaker 1: from like a room size thing to a PC to 232 00:11:37,520 --> 00:11:41,880 Speaker 1: a laptop to our phone. This this stereoscope did the 233 00:11:41,920 --> 00:11:44,600 Speaker 1: same thing. It was a big clunky thing, the steampunk version, 234 00:11:44,920 --> 00:11:48,160 Speaker 1: and then it got increasingly smaller and easier to handle 235 00:11:48,559 --> 00:11:54,080 Speaker 1: and more handy, although it was much less revolutionary than 236 00:11:54,160 --> 00:11:54,800 Speaker 1: the computer. 237 00:11:55,320 --> 00:11:58,320 Speaker 2: Yeah, they made it like, they made it more handheld. 238 00:11:58,400 --> 00:12:00,800 Speaker 2: Those in particular, there was in the eighteen forties there 239 00:12:00,840 --> 00:12:04,040 Speaker 2: was a Scottish physicist who will be pretty prominent in 240 00:12:04,080 --> 00:12:08,240 Speaker 2: this whole story named David Brewster, Sir David Brewster, and 241 00:12:08,360 --> 00:12:11,040 Speaker 2: he's the one that invented if you've ever seen one 242 00:12:11,040 --> 00:12:13,240 Speaker 2: of these in a museum or something, sort of the 243 00:12:13,240 --> 00:12:17,840 Speaker 2: early handheld version that looks like a little handheld steampunk 244 00:12:18,000 --> 00:12:19,840 Speaker 2: VR headset basically. 245 00:12:19,600 --> 00:12:23,800 Speaker 1: Yeah, like many binoculars with a slide yeah, coming out 246 00:12:23,800 --> 00:12:25,280 Speaker 1: of it that you use for focus. 247 00:12:25,520 --> 00:12:26,960 Speaker 2: Yeah, and you hold it up to your eyes and 248 00:12:27,000 --> 00:12:28,680 Speaker 2: it blocks out the rest of the light and stuff. 249 00:12:30,080 --> 00:12:35,360 Speaker 2: His more portable invention was coinciding with photography becoming more 250 00:12:35,400 --> 00:12:39,320 Speaker 2: and more developed in sort of like proper photography, and 251 00:12:39,400 --> 00:12:42,920 Speaker 2: so all of a sudden it was this popular thing, 252 00:12:43,080 --> 00:12:46,439 Speaker 2: and this was sort of the first fad of the stereogram. 253 00:12:46,440 --> 00:12:47,800 Speaker 2: There were a couple of big ones. It was one 254 00:12:47,800 --> 00:12:51,319 Speaker 2: of the nineteen nineties and one in the mid nineteenth century. 255 00:12:52,040 --> 00:12:54,600 Speaker 2: Queen Victoria went nuts for this thing in eighteen fifty 256 00:12:54,600 --> 00:12:58,640 Speaker 2: one at the Great Exhibition at Crystal Palace, and all 257 00:12:58,640 --> 00:13:01,400 Speaker 2: of a sudden, people just wanted these things to play 258 00:13:01,400 --> 00:13:03,040 Speaker 2: with and look through and marvel at. Yeah. 259 00:13:03,160 --> 00:13:06,319 Speaker 1: Right from the eighteen fifties to the nineteen thirties when 260 00:13:06,440 --> 00:13:10,440 Speaker 1: radio finally came in and took over that there was 261 00:13:10,559 --> 00:13:13,920 Speaker 1: basically not a parlor in the UK or America that 262 00:13:13,960 --> 00:13:17,160 Speaker 1: didn't have one of these things. Like you just amused 263 00:13:17,200 --> 00:13:20,080 Speaker 1: yourself with them. The fact that there were companies that 264 00:13:20,120 --> 00:13:24,640 Speaker 1: were producing hundreds of thousands or millions of different stereoscopic 265 00:13:24,720 --> 00:13:27,480 Speaker 1: images for you to look at. I mean, you could 266 00:13:27,480 --> 00:13:30,920 Speaker 1: just spend endless hours of entertainment looking at one thing 267 00:13:31,000 --> 00:13:35,840 Speaker 1: or another. And they would take images of like scenic landmarks. 268 00:13:36,040 --> 00:13:42,280 Speaker 1: Sure supposedly stereoscopic images of like Yellowstone. I think the 269 00:13:42,360 --> 00:13:48,720 Speaker 1: Yellowstone Area actually convinced congressmen back east that there actually 270 00:13:48,880 --> 00:13:53,920 Speaker 1: was an amazing wilderness out there that should that's worth preserved. Yeah, exactly. 271 00:13:53,920 --> 00:13:56,040 Speaker 1: It really made it pop. In other words, they also 272 00:13:56,120 --> 00:14:00,599 Speaker 1: very quickly started making porn with it. Everything that you 273 00:14:00,640 --> 00:14:03,240 Speaker 1: would imagine people doing when they figured out how to 274 00:14:03,280 --> 00:14:06,839 Speaker 1: make pictures that really stand out with depth, Yeah you did. 275 00:14:07,120 --> 00:14:09,640 Speaker 2: They were like, these are fantastic, but what's better than 276 00:14:09,640 --> 00:14:16,800 Speaker 2: a landscape? Ladies' ankles? Pretty much the original The original 277 00:14:16,880 --> 00:14:20,400 Speaker 2: piece of equipment used to make these were stereo cameras, 278 00:14:20,400 --> 00:14:23,640 Speaker 2: and they were these cameras with two lenses that kind 279 00:14:23,640 --> 00:14:25,480 Speaker 2: of mimic the eyes. They're said about eye with the 280 00:14:25,520 --> 00:14:28,840 Speaker 2: part and those were around for a while, and there 281 00:14:28,880 --> 00:14:32,360 Speaker 2: are still enthusiasts that own stereo cameras, as we'll see 282 00:14:32,400 --> 00:14:34,080 Speaker 2: in a little bit. That kind of figures into how 283 00:14:34,080 --> 00:14:38,080 Speaker 2: they became popular in the nineties. But in the United States, 284 00:14:38,160 --> 00:14:43,040 Speaker 2: while all this was going on, American surgeon Oliver Wendelholmes 285 00:14:43,120 --> 00:14:48,360 Speaker 2: senior papa of Oliver Wendelholmes Junior of the spring Court fame, 286 00:14:49,560 --> 00:14:52,760 Speaker 2: he's invented one in the United States and he's like, 287 00:14:52,800 --> 00:14:54,680 Speaker 2: you know what, this thing's so great, I'm not even 288 00:14:54,680 --> 00:14:57,200 Speaker 2: going to patent it. I want all kind of companies 289 00:14:57,240 --> 00:14:59,880 Speaker 2: to make these, and I want these spread far and wide. 290 00:15:00,440 --> 00:15:02,120 Speaker 2: I guess he was a surgeon, so he wouldn't hurt 291 00:15:02,200 --> 00:15:05,520 Speaker 2: her anything, right, and people, I think he's the one 292 00:15:05,520 --> 00:15:10,440 Speaker 2: that coined the term stereograph, and then the word stereogram 293 00:15:10,520 --> 00:15:12,840 Speaker 2: kind of became the go to for these images. 294 00:15:12,920 --> 00:15:15,600 Speaker 1: Yeah, everybody's like close, we're gonna switch it up just 295 00:15:15,640 --> 00:15:18,560 Speaker 1: a little bit. And still today, if you're an enthusiast 296 00:15:18,640 --> 00:15:23,720 Speaker 1: into stereoscopic photography, the stereogram is usually the term that 297 00:15:23,760 --> 00:15:24,240 Speaker 1: you'd use. 298 00:15:25,000 --> 00:15:28,240 Speaker 2: All right, I think that's a robust fifteen minutes. 299 00:15:28,480 --> 00:15:33,960 Speaker 1: Yeah, all of the nineteenth century stereogram viewers say bully, bully, bully. 300 00:15:34,400 --> 00:15:37,880 Speaker 2: That's right, bully in three D. So we'll be back 301 00:15:37,920 --> 00:15:40,560 Speaker 2: to talk about the next development, which was the auto 302 00:15:40,640 --> 00:15:42,160 Speaker 2: stereogram right after this. 303 00:15:42,720 --> 00:15:46,160 Speaker 3: If you want to know then you're in luck. Just 304 00:15:46,360 --> 00:15:53,120 Speaker 3: listen to joshcher seffus no. 305 00:15:55,560 --> 00:16:09,720 Speaker 1: Stuffus, no, all right, check. Now we finally get to 306 00:16:09,760 --> 00:16:14,440 Speaker 1: this stuff where I'm fascinated. Yeah, just riveted, right because 307 00:16:14,600 --> 00:16:20,560 Speaker 1: it's it's enough that our friends Wheatstone and Brewster contributed 308 00:16:20,920 --> 00:16:24,960 Speaker 1: the foundation to our understanding of binocular vision. But along 309 00:16:25,040 --> 00:16:27,040 Speaker 1: came in I think the nineteen fifties. 310 00:16:27,240 --> 00:16:29,360 Speaker 2: Boy, that sounds like a craft cocktail bar, isn't it. 311 00:16:30,280 --> 00:16:34,080 Speaker 1: Bruce Wheatstone Andrews like, you have to have the armband 312 00:16:34,160 --> 00:16:35,480 Speaker 1: or else you can't get employed. 313 00:16:35,480 --> 00:16:37,280 Speaker 2: There. I just got really thirsty. Sorry, go ahead. 314 00:16:37,760 --> 00:16:43,080 Speaker 1: There was a scientist a neuroscientist named Bella. ULA's had 315 00:16:43,160 --> 00:16:46,200 Speaker 1: tip to Chuck for that one who ran the Sensory 316 00:16:46,240 --> 00:16:50,880 Speaker 1: and Perceptual Processes department at AT and T Bell Labs. Again, 317 00:16:51,040 --> 00:16:55,440 Speaker 1: I think, I said in the fifties, and ULA's was, 318 00:16:55,880 --> 00:17:00,280 Speaker 1: I guess kind of focused on visual perception and figure 319 00:17:00,360 --> 00:17:02,760 Speaker 1: something out. They just like just in the same way 320 00:17:02,800 --> 00:17:06,879 Speaker 1: that that Wheatstone's invention kind of led to this neat 321 00:17:07,000 --> 00:17:07,600 Speaker 1: in this. 322 00:17:07,600 --> 00:17:09,359 Speaker 2: Neat party toy toy. 323 00:17:09,600 --> 00:17:13,919 Speaker 1: Yeah, ULA's invention kind of did the same thing, but 324 00:17:14,080 --> 00:17:17,280 Speaker 1: neither one of them were trying to create an amusement. 325 00:17:17,359 --> 00:17:20,359 Speaker 1: They were they were creating a way to prove a 326 00:17:20,440 --> 00:17:23,680 Speaker 1: hypothesis that they were interested in. And what he did 327 00:17:24,040 --> 00:17:26,439 Speaker 1: was come up with the random dot stereogram. 328 00:17:27,080 --> 00:17:31,600 Speaker 2: Yeah, so this is uh, he basically start by let's 329 00:17:31,640 --> 00:17:33,199 Speaker 2: say you have like a square or something that you 330 00:17:33,240 --> 00:17:37,320 Speaker 2: fill in randomly with black dots, and then within that 331 00:17:37,440 --> 00:17:40,959 Speaker 2: square you picked a part of it and decide on 332 00:17:41,040 --> 00:17:44,840 Speaker 2: like maybe a shape or something. So within that that square, 333 00:17:45,119 --> 00:17:47,720 Speaker 2: you'll say, all right, well, I'm gonna select a circle 334 00:17:47,760 --> 00:17:50,200 Speaker 2: within that, like maybe right in the middle, and I'm 335 00:17:50,200 --> 00:17:53,199 Speaker 2: going to create a second square that's just like the first, 336 00:17:53,720 --> 00:17:57,119 Speaker 2: except that circle in the center that I've selected is 337 00:17:57,240 --> 00:17:59,400 Speaker 2: just going to be shifted just a little bit, kind 338 00:17:59,400 --> 00:18:02,119 Speaker 2: of like we were talking about, that slight, slight difference 339 00:18:02,160 --> 00:18:05,040 Speaker 2: of perspective. Yeah, and then when you put these two 340 00:18:05,080 --> 00:18:08,160 Speaker 2: squares side by side, and when you look at these 341 00:18:08,200 --> 00:18:11,120 Speaker 2: two squares, you can look at it through a stereoscope 342 00:18:11,160 --> 00:18:13,439 Speaker 2: if you have one. But the key here is is 343 00:18:13,480 --> 00:18:15,639 Speaker 2: that he would prove that, like, hey, you can just 344 00:18:15,680 --> 00:18:18,240 Speaker 2: do this with your naked eye if you learn the 345 00:18:18,600 --> 00:18:20,879 Speaker 2: trick that people will be trying to figure out, you know, 346 00:18:21,000 --> 00:18:24,480 Speaker 2: up until twenty twenty three with future podcaster Josh Clark, 347 00:18:25,080 --> 00:18:28,600 Speaker 2: where you unFocus your eyes and then those circles appear 348 00:18:28,680 --> 00:18:30,280 Speaker 2: to sort of separate from the background. 349 00:18:30,480 --> 00:18:34,840 Speaker 1: Yeah, and so those two separate images, you still see them, 350 00:18:35,000 --> 00:18:37,000 Speaker 1: but what they do is combine to make a third 351 00:18:37,040 --> 00:18:39,640 Speaker 1: image in the center, and that's the one that has 352 00:18:39,720 --> 00:18:42,560 Speaker 1: the say, the circle popping out of it, right. 353 00:18:42,680 --> 00:18:43,240 Speaker 2: Yeah. 354 00:18:43,280 --> 00:18:47,280 Speaker 1: And Youlss obviously created the foundation for magic eye posters 355 00:18:47,359 --> 00:18:50,679 Speaker 1: with that. But what he did more than anything was 356 00:18:50,880 --> 00:18:55,280 Speaker 1: show that what our brain does when it takes in 357 00:18:55,320 --> 00:18:59,199 Speaker 1: those two separate images and slightly different perspectives because their 358 00:18:59,200 --> 00:19:05,040 Speaker 1: eyes are separated just ever so slightly, it compares basically 359 00:19:05,119 --> 00:19:10,320 Speaker 1: pixel for pixel each of the each of the images 360 00:19:10,359 --> 00:19:13,959 Speaker 1: that the eye send it and matches it up, and 361 00:19:14,000 --> 00:19:17,360 Speaker 1: then when it finds parts that don't quite match up, 362 00:19:17,840 --> 00:19:22,440 Speaker 1: it uses that to create the illusion of depth. And 363 00:19:22,520 --> 00:19:27,520 Speaker 1: that's what his random dot stereogram showed that what your 364 00:19:27,560 --> 00:19:30,640 Speaker 1: eye is doing is taking those two those two pictures 365 00:19:30,800 --> 00:19:34,239 Speaker 1: and matching up every single random dot in there and 366 00:19:34,280 --> 00:19:38,720 Speaker 1: then noticing all this is in a nanosecond, noticing what 367 00:19:39,359 --> 00:19:41,840 Speaker 1: it doesn't match up, and then that's that circle that 368 00:19:41,960 --> 00:19:45,320 Speaker 1: pops out. And then the way that he proved it 369 00:19:45,359 --> 00:19:49,719 Speaker 1: is because those two different pictures form a single image 370 00:19:49,720 --> 00:19:54,000 Speaker 1: in the center. Right, Yeah, So if you weren't looking 371 00:19:54,040 --> 00:19:56,199 Speaker 1: at two pictures, you were just using two eyes at 372 00:19:56,240 --> 00:20:00,159 Speaker 1: one picture, then that effect would still be produced. And 373 00:20:00,200 --> 00:20:02,200 Speaker 1: it really just kind of laid the foundation in showing 374 00:20:02,600 --> 00:20:07,000 Speaker 1: just exactly how our brain makes binocular vision into depth perception. 375 00:20:07,760 --> 00:20:12,480 Speaker 2: Right, So we're inching closer to the nineties and that 376 00:20:12,880 --> 00:20:17,840 Speaker 2: singular poster or coffee table book image that we all knew, 377 00:20:18,640 --> 00:20:21,280 Speaker 2: but it came to us in the nineteen seventies thanks 378 00:20:21,320 --> 00:20:25,920 Speaker 2: to a student of u Less's named Christopher Tyler, who 379 00:20:25,960 --> 00:20:30,080 Speaker 2: was a neuroscientist and he basically said, you know what, 380 00:20:30,600 --> 00:20:33,880 Speaker 2: we don't even need the two pictures. Everybody like you're 381 00:20:33,880 --> 00:20:36,880 Speaker 2: doing pretty good, but what if, like how mind blowing 382 00:20:36,920 --> 00:20:38,960 Speaker 2: would it be if we could do this all from 383 00:20:39,000 --> 00:20:43,080 Speaker 2: a single image. He called it the auto stereogram and 384 00:20:43,359 --> 00:20:46,320 Speaker 2: basically made it to where it's sort of like this, 385 00:20:47,520 --> 00:20:50,280 Speaker 2: like staring at a wallpaper. And in fact, I think 386 00:20:50,560 --> 00:20:53,560 Speaker 2: was he the one here? Then it was Brewster who 387 00:20:53,880 --> 00:20:56,280 Speaker 2: stared at wallpaper, and that's how they figured that out. 388 00:20:56,320 --> 00:20:59,520 Speaker 2: He was an odd duck, which is interesting. But Tyler 389 00:20:59,560 --> 00:21:03,160 Speaker 2: got together with a programmer named Maureen Clark and said, well, 390 00:21:03,200 --> 00:21:05,680 Speaker 2: we can probably figure this out with math, So that 391 00:21:05,720 --> 00:21:10,320 Speaker 2: they created an algorithm that could insert these images into 392 00:21:10,359 --> 00:21:13,840 Speaker 2: what looks like just almost like white noise on paper. 393 00:21:13,960 --> 00:21:15,679 Speaker 1: Yeah, And so they did away with all the crud, 394 00:21:15,760 --> 00:21:19,639 Speaker 1: those extra two images that still remain when that third 395 00:21:19,640 --> 00:21:22,600 Speaker 1: when they come together and form that illusory third image 396 00:21:22,600 --> 00:21:25,479 Speaker 1: in the middle. Yeah, so that you just see something 397 00:21:25,520 --> 00:21:27,840 Speaker 1: as you normally would see it. But if you adjust 398 00:21:27,880 --> 00:21:30,000 Speaker 1: your eyes just the right way, then that three D 399 00:21:30,040 --> 00:21:31,719 Speaker 1: image is going to come out. And now we finally 400 00:21:31,800 --> 00:21:36,080 Speaker 1: arrive in the nineteen seventies at the auto stereogram is 401 00:21:36,119 --> 00:21:40,440 Speaker 1: what they called it, which became better known eventually as 402 00:21:40,480 --> 00:21:41,560 Speaker 1: the Magic Eye poster. 403 00:21:42,520 --> 00:21:45,480 Speaker 2: Right, So, if you're listening to this and you're thinking, 404 00:21:45,840 --> 00:21:48,560 Speaker 2: all right, guys, this is the nineteen seventies. You keep 405 00:21:48,560 --> 00:21:52,080 Speaker 2: talking about the grunge era. How did we get from 406 00:21:52,080 --> 00:21:54,840 Speaker 2: the nineteen seventies to the grunge era or why didn't 407 00:21:54,840 --> 00:21:58,320 Speaker 2: we get there quicker? Basically? And one of the reasons 408 00:21:58,440 --> 00:22:02,280 Speaker 2: is this guy named Tom Shay. He's from Connecticut. He 409 00:22:02,400 --> 00:22:04,639 Speaker 2: has sort of a sounds like, sort of a hippie 410 00:22:04,640 --> 00:22:08,720 Speaker 2: dippy backstory through the nineteen sixties, working all kinds of 411 00:22:08,720 --> 00:22:11,960 Speaker 2: crazy jobs, but was like a super bright guy, a 412 00:22:12,160 --> 00:22:16,679 Speaker 2: mathematician and musician. Eventually got you know, real grown up 413 00:22:16,720 --> 00:22:20,920 Speaker 2: type jobs like helped NASA make their navigation systems, working 414 00:22:20,920 --> 00:22:24,680 Speaker 2: with a company called Intermetrics, and in the early nineties 415 00:22:24,840 --> 00:22:30,520 Speaker 2: landed at a British tech company called Pentica. And this 416 00:22:30,600 --> 00:22:33,000 Speaker 2: thing all came together really in the in the thing 417 00:22:33,000 --> 00:22:34,800 Speaker 2: that we all knew in love in the nineties because 418 00:22:34,800 --> 00:22:39,120 Speaker 2: of advertising. They had a product Pentica did called the 419 00:22:39,160 --> 00:22:43,879 Speaker 2: mime Capital mim in Circuit Emulator, and they were Boushet 420 00:22:44,000 --> 00:22:47,399 Speaker 2: was tasked to designing an ad for this thing, and 421 00:22:47,480 --> 00:22:49,560 Speaker 2: so he said, Hey, let's put a real mime in 422 00:22:49,600 --> 00:22:53,320 Speaker 2: this advertisement. It's all very serendipitous because it really is 423 00:22:53,440 --> 00:22:56,399 Speaker 2: this mime that they hired. It's either Lab or labby 424 00:22:56,520 --> 00:23:00,520 Speaker 2: Labb shows up on set and it turns out that 425 00:23:00,760 --> 00:23:05,879 Speaker 2: Lab was one of those stereo photography enthusiasts that still 426 00:23:05,920 --> 00:23:10,719 Speaker 2: had those you know, dual lensed stereo cameras. He happened 427 00:23:10,720 --> 00:23:13,080 Speaker 2: to bring this thing in on the set and Bashet 428 00:23:13,400 --> 00:23:18,000 Speaker 2: was like, OMG, what is that thing and just was like, 429 00:23:18,240 --> 00:23:20,199 Speaker 2: sounds like it was just instantly sort of taken with 430 00:23:20,240 --> 00:23:20,760 Speaker 2: his idea. 431 00:23:20,960 --> 00:23:23,800 Speaker 1: Yeah, he said it was the most compelling optical illusion 432 00:23:23,920 --> 00:23:24,879 Speaker 1: I'd ever seen. 433 00:23:25,320 --> 00:23:26,760 Speaker 2: There you haven't in his own words. 434 00:23:27,000 --> 00:23:30,119 Speaker 1: So what he did he said, Okay, I really appreciate 435 00:23:30,160 --> 00:23:31,959 Speaker 1: your help here, so I'm going to keep going with 436 00:23:32,000 --> 00:23:34,320 Speaker 1: this mime ad, but I'm also going to try to 437 00:23:34,359 --> 00:23:38,280 Speaker 1: make another ad using one of these auto stereograms, and 438 00:23:38,320 --> 00:23:41,560 Speaker 1: he did. He made one that had the hidden message 439 00:23:41,680 --> 00:23:45,720 Speaker 1: M seven hundred, which was a version of their in 440 00:23:45,840 --> 00:23:48,040 Speaker 1: circuit emulator that his company made. 441 00:23:48,359 --> 00:23:50,080 Speaker 2: Which who knows what that is. I even tried to 442 00:23:50,080 --> 00:23:50,640 Speaker 2: figure it out. 443 00:23:51,040 --> 00:23:54,439 Speaker 1: So the best I could see is that it's a like, 444 00:23:54,720 --> 00:23:58,680 Speaker 1: rather than using your computer to figure out if a 445 00:23:58,720 --> 00:24:03,720 Speaker 1: circuit like a microprocess or a circuit board works. This 446 00:24:03,800 --> 00:24:08,600 Speaker 1: thing emulates either your computer or a circuit board so 447 00:24:08,640 --> 00:24:11,960 Speaker 1: that you can find individual bugs and fix them. That's 448 00:24:12,000 --> 00:24:14,879 Speaker 1: the best I could come up with. It's still very confusing, 449 00:24:14,920 --> 00:24:16,399 Speaker 1: but that's yeah, that's that. 450 00:24:16,880 --> 00:24:19,520 Speaker 2: And just so as a listener, you're not confused. That 451 00:24:19,560 --> 00:24:21,600 Speaker 2: has nothing to do with what happened. It was just 452 00:24:21,640 --> 00:24:25,359 Speaker 2: a product. It could have been a widget or whatever, definitely, 453 00:24:26,240 --> 00:24:28,960 Speaker 2: but the idea was it was another ad that he 454 00:24:29,040 --> 00:24:33,359 Speaker 2: actually used the technology to make a autostereogram for this ad. 455 00:24:33,520 --> 00:24:38,040 Speaker 1: And this ad was so it made such an impression 456 00:24:38,040 --> 00:24:40,720 Speaker 1: on people that it made it out of the pages 457 00:24:40,840 --> 00:24:48,080 Speaker 1: of Embedded Systems Engineering Magazine into something of like the 458 00:24:48,160 --> 00:24:51,560 Speaker 1: general corporate culture. And all of a sudden, at his 459 00:24:51,680 --> 00:24:57,480 Speaker 1: desk at Pentica, but Shea starts getting faxes from people saying, Hey, 460 00:24:57,760 --> 00:25:00,760 Speaker 1: can you make me and my company one of those 461 00:25:00,920 --> 00:25:04,560 Speaker 1: really neat ads that you made? And he ended up 462 00:25:04,640 --> 00:25:08,560 Speaker 1: kind of creating like a little mini side job for himself, 463 00:25:09,880 --> 00:25:14,320 Speaker 1: creating custom auto stereograms for people who faxed him and 464 00:25:14,359 --> 00:25:14,919 Speaker 1: asked for him. 465 00:25:15,520 --> 00:25:19,080 Speaker 2: Yeah, he was no artist, though, so very smartly. In 466 00:25:19,160 --> 00:25:21,640 Speaker 2: nineteen ninety one, he hooked up with a woman named 467 00:25:21,640 --> 00:25:26,000 Speaker 2: Sherry Smith, who was an artist, a freelancer, and I 468 00:25:26,000 --> 00:25:30,200 Speaker 2: think was also a computer graphics person, and so he said, 469 00:25:30,359 --> 00:25:32,720 Speaker 2: you're perfect. You're an artist and you know computer graphics, 470 00:25:33,040 --> 00:25:35,639 Speaker 2: so you can kick this thing up a notch and 471 00:25:36,119 --> 00:25:38,520 Speaker 2: basically make images that are a little more interesting to 472 00:25:38,520 --> 00:25:41,800 Speaker 2: look at. But it was still sort of an advertising 473 00:25:41,800 --> 00:25:45,040 Speaker 2: thing because they made one for American Airlines for their 474 00:25:45,080 --> 00:25:49,080 Speaker 2: in flight magazine that was really popular and apparently for 475 00:25:49,160 --> 00:25:51,639 Speaker 2: a while at least they would give away a bottle 476 00:25:51,640 --> 00:25:54,720 Speaker 2: of champagne. I would think a glass, but I guess 477 00:25:54,720 --> 00:25:57,080 Speaker 2: a bottle of champagne to the first person on the 478 00:25:57,119 --> 00:25:59,639 Speaker 2: flight who could find the image and say what it was. 479 00:26:00,119 --> 00:26:03,760 Speaker 2: Of course it was an airplane. But after the American 480 00:26:03,800 --> 00:26:07,040 Speaker 2: Airlines ad thing, Boshe was like, wait a minute, like 481 00:26:07,080 --> 00:26:09,480 Speaker 2: people are going nuts for this in ads. But I think, 482 00:26:09,600 --> 00:26:11,320 Speaker 2: like people are going so crazy for this, I think 483 00:26:11,359 --> 00:26:13,720 Speaker 2: we could just sell these somehow, right. 484 00:26:13,880 --> 00:26:17,439 Speaker 1: Take his job for making these four other companies and 485 00:26:17,520 --> 00:26:19,800 Speaker 1: just make them and sell them directly to the public. 486 00:26:20,040 --> 00:26:22,840 Speaker 1: And he actually started out doing mail order. He was 487 00:26:22,960 --> 00:26:25,760 Speaker 1: he realized he was onto something because he started doing 488 00:26:25,800 --> 00:26:28,520 Speaker 1: mail order in order to try to kick off a 489 00:26:28,560 --> 00:26:31,600 Speaker 1: fad that he could then go and license to other 490 00:26:31,680 --> 00:26:34,800 Speaker 1: people or partner with a big company and make himself 491 00:26:34,840 --> 00:26:38,040 Speaker 1: that much more desirable. He really approached this in a 492 00:26:38,080 --> 00:26:38,880 Speaker 1: smart way. 493 00:26:39,040 --> 00:26:41,880 Speaker 2: A kickstarter of the time probably was mail order exactly. 494 00:26:41,960 --> 00:26:44,480 Speaker 1: Yeah, that's a really great analogy. And he created a 495 00:26:44,640 --> 00:26:47,280 Speaker 1: company or either he created it or he already had 496 00:26:47,320 --> 00:26:52,240 Speaker 1: it and repurposed it. N period e period thing enterprises. 497 00:26:52,560 --> 00:26:57,320 Speaker 2: Very clever, very very clever anything. Yeah, and he dieted everyone. 498 00:26:57,440 --> 00:27:01,359 Speaker 1: He just one hundred percent, just to make sure instead 499 00:27:01,359 --> 00:27:05,040 Speaker 1: of N period e period what you're really saying is 500 00:27:05,160 --> 00:27:06,160 Speaker 1: a and y. 501 00:27:06,840 --> 00:27:09,280 Speaker 2: Thing anything anything. 502 00:27:09,320 --> 00:27:13,320 Speaker 1: We're anything enterprises, right, so anything N period e period 503 00:27:13,440 --> 00:27:18,199 Speaker 1: Thing Enterprises partnered with a Japanese company called Tenyoh and 504 00:27:18,280 --> 00:27:21,919 Speaker 1: Tenya was a magic trick maker. They still are as 505 00:27:21,960 --> 00:27:26,520 Speaker 1: far as I can tell, and they said, this actually 506 00:27:27,160 --> 00:27:30,000 Speaker 1: is amazing, and we think our friends in Japan are 507 00:27:30,000 --> 00:27:31,800 Speaker 1: going to go crazy for it, and they licensed it 508 00:27:31,880 --> 00:27:35,879 Speaker 1: and started publishing books based on the Magic Eye what 509 00:27:35,920 --> 00:27:38,280 Speaker 1: would come to be No Magic Eye as Magic Eye, 510 00:27:38,320 --> 00:27:40,400 Speaker 1: And apparently it was the ten Year company that said, 511 00:27:40,600 --> 00:27:42,520 Speaker 1: let's call it Magic Eye because the name you have 512 00:27:42,640 --> 00:27:43,640 Speaker 1: for it is stupid. 513 00:27:44,359 --> 00:27:48,040 Speaker 2: I disagree. They called it Magic Eye because, like you said, 514 00:27:48,040 --> 00:27:49,680 Speaker 2: they were a magic trick company and had a line 515 00:27:49,720 --> 00:27:53,199 Speaker 2: of magic this, magic that. But I think Boushat's original 516 00:27:53,320 --> 00:28:00,000 Speaker 2: name stereos hyphen or I guess Kama the Amazing Thing 517 00:28:00,400 --> 00:28:03,280 Speaker 2: gays toys, So you have to spell it out well, 518 00:28:03,400 --> 00:28:06,600 Speaker 2: S T A R E stare stereos. I kind of 519 00:28:06,640 --> 00:28:09,359 Speaker 2: like that. I think it's catchy. You forgot the hyphens, No, 520 00:28:09,680 --> 00:28:12,560 Speaker 2: S T A R E hyphen e hyphens right. 521 00:28:13,080 --> 00:28:16,440 Speaker 1: You know who would love this bishet? Guys Jonathan Strickland. Yeah, 522 00:28:16,560 --> 00:28:19,280 Speaker 1: he's a puny type, so I think Strickland would be like, 523 00:28:19,359 --> 00:28:20,879 Speaker 1: You're my kind of guy, for sure. 524 00:28:21,680 --> 00:28:24,280 Speaker 2: I think you should tell everyone, though, the great great 525 00:28:24,400 --> 00:28:28,399 Speaker 2: name of or rather the great translated name of the 526 00:28:28,880 --> 00:28:31,200 Speaker 2: first book that they put out in Japan of these. 527 00:28:31,160 --> 00:28:34,600 Speaker 1: So thank you for that. It's called Muru Muru Mega 528 00:28:35,080 --> 00:28:37,520 Speaker 1: yaka Nadu MAGICI. 529 00:28:37,760 --> 00:28:40,040 Speaker 2: Which means translated. 530 00:28:39,560 --> 00:28:42,200 Speaker 1: Your eyesight gets better and better in a very short 531 00:28:42,280 --> 00:28:44,280 Speaker 1: rate of time. Colon MAGICI. 532 00:28:45,440 --> 00:28:48,400 Speaker 2: That's so good, and it was a hit. 533 00:28:48,480 --> 00:28:50,960 Speaker 1: Apparently it was the best seller. Very quickly I think 534 00:28:50,960 --> 00:28:53,560 Speaker 1: they started I read they started selling them on street 535 00:28:53,600 --> 00:28:57,120 Speaker 1: corners and then very quickly after that, the first print, 536 00:28:57,520 --> 00:28:59,880 Speaker 1: the first printing ran out and they they made an 537 00:29:00,280 --> 00:29:01,960 Speaker 1: huge run and that sold out, and it was just 538 00:29:02,080 --> 00:29:04,920 Speaker 1: a hit in Japan. And it's interesting it went from 539 00:29:05,120 --> 00:29:09,160 Speaker 1: America to Japan and then back to America where it 540 00:29:09,240 --> 00:29:10,360 Speaker 1: really kind of blew up. 541 00:29:11,200 --> 00:29:14,160 Speaker 2: Yeah, I guess Bashad didn't have from what I could tell, 542 00:29:15,120 --> 00:29:17,960 Speaker 2: he was partnered in Japan, but I guess still had 543 00:29:18,000 --> 00:29:21,680 Speaker 2: the rights to do it in the United States, even though, 544 00:29:21,680 --> 00:29:24,800 Speaker 2: as we'll see, like he didn't own this idea like 545 00:29:24,840 --> 00:29:27,520 Speaker 2: no one did, because other people came along later. It 546 00:29:27,640 --> 00:29:30,320 Speaker 2: was it wasn't like a specific technology you could patent 547 00:29:30,440 --> 00:29:33,640 Speaker 2: or anything. But he was the first person in the US, 548 00:29:33,640 --> 00:29:37,360 Speaker 2: it looks like, to bring it over here and partner 549 00:29:37,440 --> 00:29:41,200 Speaker 2: with a guy named Bob Slitski who was a former 550 00:29:41,560 --> 00:29:45,800 Speaker 2: colleague at Pentica. And it sounds like Slitski was a 551 00:29:45,800 --> 00:29:49,920 Speaker 2: guy who just made a more robust computer program to 552 00:29:50,040 --> 00:29:52,080 Speaker 2: automate the stuff, to make it easier to come up 553 00:29:52,080 --> 00:29:55,920 Speaker 2: with different images, and then also colorize it so they 554 00:29:55,960 --> 00:29:58,640 Speaker 2: were previously black and white, and all of a sudden 555 00:29:58,880 --> 00:30:03,080 Speaker 2: you could do these things which made them look sharper. Evidently, 556 00:30:04,240 --> 00:30:07,440 Speaker 2: they hooked up with a licensing agent named Mark Gregorrek 557 00:30:07,960 --> 00:30:10,680 Speaker 2: who said, hey, this thing like we could license the 558 00:30:10,720 --> 00:30:12,280 Speaker 2: cred out of this person. Thing we had to do 559 00:30:12,400 --> 00:30:14,600 Speaker 2: was get in a book, which they did in nineteen 560 00:30:14,640 --> 00:30:17,920 Speaker 2: ninety three, and that was that very first what ended 561 00:30:17,960 --> 00:30:20,920 Speaker 2: up being super popular Magic eyebook. 562 00:30:21,440 --> 00:30:23,680 Speaker 1: Yeah. I mean, think about how Saren dippis it is, 563 00:30:23,720 --> 00:30:26,120 Speaker 1: starting with Ron lab and then all of the people 564 00:30:26,200 --> 00:30:28,680 Speaker 1: he met along the way who ended up making this 565 00:30:28,840 --> 00:30:32,080 Speaker 1: the fad that it became. He really lucked out. He 566 00:30:32,120 --> 00:30:37,320 Speaker 1: fell backwards into something really interesting. But they released a 567 00:30:37,360 --> 00:30:39,760 Speaker 1: bunch of books. But while the first Magic Eyebook in 568 00:30:39,760 --> 00:30:42,680 Speaker 1: the United States was still fresh on the best seller list, 569 00:30:42,760 --> 00:30:44,880 Speaker 1: they released a second one and that quickly joined the 570 00:30:44,880 --> 00:30:47,800 Speaker 1: first one on the best seller list. America just went 571 00:30:47,920 --> 00:30:48,920 Speaker 1: nuts for these things. 572 00:30:49,040 --> 00:30:49,320 Speaker 2: Yeah. 573 00:30:49,440 --> 00:30:51,600 Speaker 1: One reason it went nuts is because there was a 574 00:30:51,640 --> 00:30:56,480 Speaker 1: certain measure of superiority that you could hold people who. 575 00:30:56,320 --> 00:30:58,000 Speaker 2: Couldn't do it, like you'd see it. 576 00:30:58,040 --> 00:31:01,600 Speaker 1: There were people out there, including me, you just couldn't 577 00:31:02,120 --> 00:31:04,200 Speaker 1: do it, and you just get so mad and frustrated, 578 00:31:04,200 --> 00:31:06,360 Speaker 1: and people who could do it found that really satisfying. 579 00:31:06,400 --> 00:31:07,480 Speaker 1: I've always suspected. 580 00:31:07,960 --> 00:31:10,239 Speaker 2: Yeah, it took me a while. It wasn't like I 581 00:31:10,320 --> 00:31:13,480 Speaker 2: instantaneously got it. But I eventually did. And that was 582 00:31:13,600 --> 00:31:15,320 Speaker 2: kind of the joke in Mall Rats. I don't know 583 00:31:15,320 --> 00:31:18,440 Speaker 2: if you ever saw that movie. I didn't, but it was, 584 00:31:18,880 --> 00:31:22,040 Speaker 2: you know, the Kevin Smith movie, I guess, right after 585 00:31:22,080 --> 00:31:25,320 Speaker 2: Clerk's and Ethan Suppley, like I said, would stare and 586 00:31:25,360 --> 00:31:27,600 Speaker 2: stare at it, and people were making fun of him, 587 00:31:27,640 --> 00:31:30,440 Speaker 2: and like there's one scene like these two little kids 588 00:31:30,480 --> 00:31:32,840 Speaker 2: came up and like got it right away, and he 589 00:31:32,960 --> 00:31:34,280 Speaker 2: just gets more and more frustrated. 590 00:31:34,320 --> 00:31:35,720 Speaker 1: So he's for that. 591 00:31:36,000 --> 00:31:37,840 Speaker 2: Yeah, that's sort of playing into what you were talking 592 00:31:37,880 --> 00:31:39,640 Speaker 2: about with just like feeling like a dummy if you 593 00:31:39,640 --> 00:31:40,160 Speaker 2: couldn't get it. 594 00:31:40,240 --> 00:31:42,800 Speaker 1: Yeah, and that definitely was a thing. I've read, you 595 00:31:42,840 --> 00:31:45,920 Speaker 1: know a number of like kind of retrospectives about it, 596 00:31:46,040 --> 00:31:48,280 Speaker 1: and most of them were from people who couldn't get it, 597 00:31:48,320 --> 00:31:51,720 Speaker 1: and they still seemed slightly bitter, but they still can't 598 00:31:51,720 --> 00:31:54,560 Speaker 1: get it, you know, thirty years on or whatever. But 599 00:31:55,360 --> 00:31:58,320 Speaker 1: it was. It was enormous, not just at mal kiosks, 600 00:31:58,360 --> 00:32:01,600 Speaker 1: but in books. There is a comic strip that's still 601 00:32:01,600 --> 00:32:04,320 Speaker 1: around that you can license through UPI if you want. 602 00:32:05,280 --> 00:32:09,400 Speaker 1: It showed up on Honeynut Cheerios boxes. There were postcards, 603 00:32:09,680 --> 00:32:11,880 Speaker 1: other companies came a call in and said, hey, we 604 00:32:11,920 --> 00:32:13,800 Speaker 1: want you to make some of these for us, like Disney. 605 00:32:14,000 --> 00:32:17,440 Speaker 1: I think CBS had them do something for like one 606 00:32:17,480 --> 00:32:22,000 Speaker 1: of their internal sales booklets. It just started showing up everywhere, 607 00:32:22,360 --> 00:32:26,120 Speaker 1: and I think the cream of the crop of like 608 00:32:26,400 --> 00:32:29,680 Speaker 1: additional stuff that came out of this was a book 609 00:32:29,760 --> 00:32:33,680 Speaker 1: that Boshet put together, a magic eyebook for Christmas called 610 00:32:33,720 --> 00:32:36,120 Speaker 1: do you See What I See? 611 00:32:37,120 --> 00:32:39,080 Speaker 2: That just presses Yeah, that's good. 612 00:32:39,120 --> 00:32:41,720 Speaker 1: I couldn't find one. I found a Christmas themed one, 613 00:32:41,760 --> 00:32:43,080 Speaker 1: but I don't think it was from the do you 614 00:32:43,160 --> 00:32:43,880 Speaker 1: See What I See? 615 00:32:43,880 --> 00:32:48,120 Speaker 2: Book? That's disappointing. It was a little bit so Bishey 616 00:32:48,560 --> 00:32:54,080 Speaker 2: basically said in nineteen ninety four, in one year he 617 00:32:54,280 --> 00:32:57,680 Speaker 2: estimates that they raked in between two hundred and a 618 00:32:57,720 --> 00:33:01,440 Speaker 2: quarter of a million bucks or sorry, quarter of a 619 00:33:01,480 --> 00:33:04,440 Speaker 2: billion billion dollars and hundred and fifty million. 620 00:33:04,520 --> 00:33:05,800 Speaker 1: Yeah, and that was I think the peak here in 621 00:33:05,840 --> 00:33:09,200 Speaker 1: ninety three or ninety four was it was huge. 622 00:33:09,480 --> 00:33:15,160 Speaker 2: All right, So Bashe is going strong. Early nineties, Like 623 00:33:15,200 --> 00:33:18,560 Speaker 2: I said, no one owned this idea. It's not a 624 00:33:18,560 --> 00:33:22,120 Speaker 2: particular technology. So people started jumping on board and doing 625 00:33:22,160 --> 00:33:25,240 Speaker 2: their own and the main standout to me, I think 626 00:33:25,360 --> 00:33:28,360 Speaker 2: is are the guys who if you saw them at 627 00:33:28,360 --> 00:33:31,800 Speaker 2: the mall kiosks, you probably saw the version from a 628 00:33:31,840 --> 00:33:34,640 Speaker 2: company called Hallusion art Prints. 629 00:33:34,600 --> 00:33:36,760 Speaker 1: And art prints emphasis on art I think. 630 00:33:37,560 --> 00:33:41,840 Speaker 2: Yeah. And so these guys, Paul Huber, who's an aerospace engineer, 631 00:33:41,880 --> 00:33:46,440 Speaker 2: and a software engineer named Mike Belinsky, they were turned 632 00:33:46,440 --> 00:33:48,120 Speaker 2: on by these things too, and they said, hey, this 633 00:33:48,240 --> 00:33:50,960 Speaker 2: is pretty great. We're two smart guys. We can build 634 00:33:50,960 --> 00:33:54,800 Speaker 2: our own computer program and algorithm to make these things ourselves. 635 00:33:54,880 --> 00:33:58,640 Speaker 2: And they started making these posters in ninety two, and 636 00:33:59,000 --> 00:34:01,840 Speaker 2: that those were the Hallusion art prints that you would 637 00:34:02,120 --> 00:34:03,680 Speaker 2: most likely those are the ones. Like I said that 638 00:34:03,720 --> 00:34:06,080 Speaker 2: you were seeing it at the kiosk for about twenty 639 00:34:06,120 --> 00:34:08,760 Speaker 2: to twenty five bucks. These guys were printing these things 640 00:34:08,760 --> 00:34:13,879 Speaker 2: for a quarter. Even with like if they're wholesaling these 641 00:34:13,880 --> 00:34:16,440 Speaker 2: things to the kiosk, they're still making some pretty good 642 00:34:16,480 --> 00:34:17,920 Speaker 2: dough off of that. Yeah, kind of mark. 643 00:34:17,840 --> 00:34:20,520 Speaker 1: Maybe ten bucks something like that off. 644 00:34:20,400 --> 00:34:23,160 Speaker 2: A poster awsome a quarter. It's good return. 645 00:34:23,280 --> 00:34:26,279 Speaker 1: Heck, yeah it is. And they started churning these things out. 646 00:34:26,320 --> 00:34:28,520 Speaker 1: But like I said, there's an emphasis on art prints, 647 00:34:28,560 --> 00:34:30,960 Speaker 1: Like they kind of saw theirs as it was different. 648 00:34:31,000 --> 00:34:33,879 Speaker 1: It was distinguished from the other ones because they were 649 00:34:33,920 --> 00:34:36,920 Speaker 1: just so well made. The problem is is people are like, 650 00:34:37,239 --> 00:34:39,520 Speaker 1: that's great, I can still get the same effect from 651 00:34:39,560 --> 00:34:41,919 Speaker 1: a similar one from one of your competitors for five 652 00:34:42,000 --> 00:34:45,120 Speaker 1: dollars at Spencer's rather than twenty five dollars at your 653 00:34:45,400 --> 00:34:48,920 Speaker 1: admittedly very charming Kiosk. Right, I'm gonna go with the 654 00:34:48,960 --> 00:34:52,200 Speaker 1: five dollars one. And so they set themselves up for 655 00:34:52,280 --> 00:34:54,239 Speaker 1: some pretty serious competition out of the gate. 656 00:34:54,840 --> 00:34:57,520 Speaker 2: Yeah, big time. And there are all kinds of people 657 00:34:57,560 --> 00:35:00,440 Speaker 2: pumping these things out. But like you said, you go 658 00:35:00,520 --> 00:35:03,200 Speaker 2: to the Kiosk, you get your ears pierced, sure by 659 00:35:03,200 --> 00:35:07,920 Speaker 2: a top quality seventeen year old twenty five times. Excuse me, 660 00:35:08,360 --> 00:35:11,439 Speaker 2: Oh don't know. I meant purchase a top quality poster. Okay, 661 00:35:11,480 --> 00:35:13,120 Speaker 2: but yeah, you're also getting your ear piers by a 662 00:35:13,160 --> 00:35:18,080 Speaker 2: top quality seventeen Claire's piercing Pagoda or Claies or something. 663 00:35:19,480 --> 00:35:22,680 Speaker 2: So Basha their company started to fade a little bit 664 00:35:22,719 --> 00:35:26,400 Speaker 2: because of the competition, and he thought, like when he 665 00:35:26,440 --> 00:35:31,239 Speaker 2: was interviewed in ninety four by Ink magazine, he thought 666 00:35:31,280 --> 00:35:33,560 Speaker 2: this was like, Hey, this is the beginning. We're going 667 00:35:33,640 --> 00:35:36,799 Speaker 2: to be huge. His literal quote was talking about being 668 00:35:36,840 --> 00:35:40,440 Speaker 2: a Disney of the twenty first century and like making 669 00:35:40,480 --> 00:35:43,879 Speaker 2: it into a big multimedia company. And then many years later, 670 00:35:44,040 --> 00:35:48,200 Speaker 2: in like the late twenty sixteen or twenty seventeen, he 671 00:35:49,080 --> 00:35:52,760 Speaker 2: reflected back and said, well, as it turns out, maybe 672 00:35:52,760 --> 00:35:55,480 Speaker 2: that was just my fifteen minutes and it wasn't that 673 00:35:55,560 --> 00:35:58,560 Speaker 2: much fun and it was really exhausting. He ended up 674 00:35:58,600 --> 00:36:03,680 Speaker 2: selling his majority State and Anything to Smith and another 675 00:36:03,719 --> 00:36:07,239 Speaker 2: one of the employees there who renamed it Magic Eye 676 00:36:07,640 --> 00:36:10,879 Speaker 2: and Smith's Cherry Smith still owns the company today. 677 00:36:10,960 --> 00:36:13,879 Speaker 1: Yeah, that original graphic artist he first partnered with, which 678 00:36:13,880 --> 00:36:15,200 Speaker 1: is pretty cool. I think that's great. 679 00:36:15,239 --> 00:36:16,960 Speaker 2: Yeah, you know, I bet they still make some dough 680 00:36:16,960 --> 00:36:17,800 Speaker 2: off of this. Yeah. 681 00:36:17,880 --> 00:36:21,840 Speaker 1: Can you imagine if today we were you know, you'd 682 00:36:21,880 --> 00:36:26,000 Speaker 1: tell your friend I'm going to Anything Enterprises this summer 683 00:36:26,360 --> 00:36:30,720 Speaker 1: and then we say World or Land. Yeah, just doesn't 684 00:36:30,760 --> 00:36:34,200 Speaker 1: quite have that ring, you know, No, it doesn't. So, Yeah, 685 00:36:34,239 --> 00:36:37,440 Speaker 1: that fad ran its course. Even during the heat of it. 686 00:36:37,520 --> 00:36:40,520 Speaker 1: Everybody but Boshet was well aware this is a fad, 687 00:36:41,000 --> 00:36:43,880 Speaker 1: and he knew, but he was hoping beyond hope that 688 00:36:43,960 --> 00:36:47,520 Speaker 1: he could turn it and parlay it into something else. Right. Yeah, 689 00:36:47,520 --> 00:36:50,000 Speaker 1: But as much as the rest of the world kind 690 00:36:50,000 --> 00:36:53,640 Speaker 1: of moved on from stereograms. They proved to be a 691 00:36:53,760 --> 00:37:02,600 Speaker 1: really useful training technique for people whose eyes don't align 692 00:37:02,680 --> 00:37:08,600 Speaker 1: properly because of poor muscular development, people with strabismus in particular. 693 00:37:09,280 --> 00:37:13,239 Speaker 2: Yeah, it almost they'll do like these little exercises. I'll 694 00:37:13,239 --> 00:37:15,400 Speaker 2: give you these exercises to do, and it's almost like 695 00:37:15,640 --> 00:37:18,960 Speaker 2: a workout for your eyeball, right, to build that muscle 696 00:37:18,960 --> 00:37:19,279 Speaker 2: back up. 697 00:37:19,360 --> 00:37:22,680 Speaker 1: Yeah, exactly. Apparently there's a critical window when you're young, 698 00:37:23,360 --> 00:37:26,839 Speaker 1: I think up to about three maybe four where your 699 00:37:26,880 --> 00:37:31,080 Speaker 1: brain learns to put together the two different pictures that 700 00:37:31,120 --> 00:37:34,239 Speaker 1: it's eye, your eyes are giving it into one cohesive hole, 701 00:37:34,600 --> 00:37:37,480 Speaker 1: and that if your eyes aren't aligned properly, or there's 702 00:37:37,520 --> 00:37:40,239 Speaker 1: another condition where one eye is way more dominant than 703 00:37:40,280 --> 00:37:43,759 Speaker 1: the other, your brain just disregards the picture from the 704 00:37:43,840 --> 00:37:47,319 Speaker 1: non dominant or non aligned eye and just relies on 705 00:37:47,440 --> 00:37:52,040 Speaker 1: the dominant or you know, straight eye and you don't 706 00:37:52,080 --> 00:37:54,880 Speaker 1: see in depth. You just have monocular vision. You're getting 707 00:37:54,920 --> 00:37:57,520 Speaker 1: information from both eyes. They both work just fine, but 708 00:37:57,600 --> 00:38:00,680 Speaker 1: your brain's just disregarding one and so you you're what's 709 00:38:00,680 --> 00:38:04,240 Speaker 1: called stereo blind. And they can correct that through surgery. 710 00:38:04,280 --> 00:38:08,160 Speaker 1: But after surgery, they start showing you magic eye posters 711 00:38:08,200 --> 00:38:09,120 Speaker 1: to train yourself. 712 00:38:09,920 --> 00:38:13,759 Speaker 2: Yeah, Ruby had something. It wasn't exactly this, but she 713 00:38:14,040 --> 00:38:17,279 Speaker 2: has has always had like when she's really tired, one 714 00:38:17,320 --> 00:38:20,680 Speaker 2: of her eyes can go wonky. Yeah it is. And 715 00:38:20,800 --> 00:38:22,279 Speaker 2: when she was little she wore a patch for a 716 00:38:22,320 --> 00:38:25,520 Speaker 2: little while and then you know, we've kept taking her 717 00:38:25,520 --> 00:38:27,160 Speaker 2: to the to the eye doctor all these years and 718 00:38:27,200 --> 00:38:30,080 Speaker 2: they finally were like, you know, it's fine, Like she's 719 00:38:30,120 --> 00:38:33,560 Speaker 2: she's basically corrected it. It still happens sometimes when she's 720 00:38:33,560 --> 00:38:36,759 Speaker 2: super tired, and I'll just say, I'll say, maybe, you know, 721 00:38:36,800 --> 00:38:40,120 Speaker 2: snap your eyes together, and she go zoop and she can. 722 00:38:40,200 --> 00:38:42,680 Speaker 2: She can do it on purpose, so she kind of 723 00:38:42,760 --> 00:38:46,040 Speaker 2: learned how to control it. I guess that's pretty cute. Yeah, 724 00:38:46,040 --> 00:38:46,640 Speaker 2: it's interesting. 725 00:38:46,920 --> 00:38:52,040 Speaker 1: So if you wanted to make a magic eye puzzle, Uh, 726 00:38:52,080 --> 00:38:55,160 Speaker 1: there's just a few things you need to know. Actually 727 00:38:55,160 --> 00:38:57,400 Speaker 1: you do. You don't really need to know anything about 728 00:38:57,400 --> 00:39:02,000 Speaker 1: it because today there's so many free like like stereogram 729 00:39:02,080 --> 00:39:04,279 Speaker 1: building software available. 730 00:39:05,400 --> 00:39:06,840 Speaker 2: You know, you need to know how to type the 731 00:39:06,840 --> 00:39:08,800 Speaker 2: word sailboat pretty much. 732 00:39:09,200 --> 00:39:11,440 Speaker 1: As a matter of fact, I was looking on how 733 00:39:11,480 --> 00:39:14,480 Speaker 1: to make a stereogram. I found an Instructibles article and 734 00:39:14,520 --> 00:39:17,080 Speaker 1: I opened it up said eight steps to making a 735 00:39:17,200 --> 00:39:22,560 Speaker 1: stereogram or auto stereogram image. Step one was download a 736 00:39:22,600 --> 00:39:29,000 Speaker 1: stereogram maker program. Key, yeah, exactly. But what you're doing is, 737 00:39:29,960 --> 00:39:31,400 Speaker 1: i'd say, we just kind of talk about how they 738 00:39:31,400 --> 00:39:33,359 Speaker 1: work real quick, okay before we eat. 739 00:39:33,440 --> 00:39:33,640 Speaker 3: Yeah. 740 00:39:34,080 --> 00:39:36,080 Speaker 2: I still don't quite get it. I mean I kind 741 00:39:36,120 --> 00:39:37,960 Speaker 2: of know how you can see one, but I still 742 00:39:38,000 --> 00:39:39,239 Speaker 2: don't quite get how they're made. 743 00:39:40,840 --> 00:39:45,400 Speaker 1: Oh I don't either. Ohh so mean, okay, I don't. 744 00:39:45,440 --> 00:39:48,040 Speaker 1: Actually there's a little bit that I kind of understand. 745 00:39:48,080 --> 00:39:53,160 Speaker 1: But from what I gather, they you take your image 746 00:39:53,600 --> 00:39:56,799 Speaker 1: and you make it separately. Right, So when you're when 747 00:39:56,840 --> 00:39:59,719 Speaker 1: you're looking at a magic I poster, there's usually not 748 00:39:59,800 --> 00:40:02,399 Speaker 1: much detail, especially in the ones from the nineties. It's 749 00:40:02,480 --> 00:40:05,560 Speaker 1: a star, it's a ball, it's a I think it's 750 00:40:05,560 --> 00:40:09,640 Speaker 1: a dragon kind of thing. It's just an outline a silhouette. 751 00:40:09,719 --> 00:40:13,400 Speaker 1: And they've gotten way more sophisticated since then to I 752 00:40:13,520 --> 00:40:15,919 Speaker 1: saw one today that was a squirrel and you could 753 00:40:15,920 --> 00:40:18,200 Speaker 1: see the pupil in the squirrel's eye like it was 754 00:40:18,440 --> 00:40:19,760 Speaker 1: really sophisticated. 755 00:40:19,960 --> 00:40:20,720 Speaker 2: Oh wow, they've. 756 00:40:20,560 --> 00:40:23,240 Speaker 1: Gotten really good at it. But what they do whether 757 00:40:23,280 --> 00:40:27,879 Speaker 1: it's primitive or really sophisticated. They're taking that image making 758 00:40:27,960 --> 00:40:31,600 Speaker 1: a silhouette, but they're giving the silhouette depth using gray scale. 759 00:40:32,000 --> 00:40:35,880 Speaker 1: So the lighter the gray color shading there is to 760 00:40:35,960 --> 00:40:39,000 Speaker 1: the silhouette, the closer it is to you, the darker 761 00:40:39,040 --> 00:40:41,160 Speaker 1: it is, the further way it is. Just like you 762 00:40:41,160 --> 00:40:44,359 Speaker 1: wouldn't like a regular like a charcoal drawing of something, right, 763 00:40:44,600 --> 00:40:47,600 Speaker 1: except there's nothing in the middle. And then the computer 764 00:40:47,800 --> 00:40:52,080 Speaker 1: program takes that computer generated image and it assigns different 765 00:40:52,160 --> 00:40:56,120 Speaker 1: values depending on how light or dark along the gray 766 00:40:56,160 --> 00:40:59,800 Speaker 1: scale each pixel is, and that's how much it gets displaced. 767 00:41:00,000 --> 00:41:03,280 Speaker 1: The lighter it is, the further away it gets just placed, 768 00:41:03,400 --> 00:41:06,360 Speaker 1: the more it's gonna pop out towards you, which indicates 769 00:41:06,400 --> 00:41:09,600 Speaker 1: that this part of the pictures in the foreground, it's 770 00:41:09,680 --> 00:41:12,240 Speaker 1: closer to you than say the rump of the squirrel. 771 00:41:12,880 --> 00:41:15,399 Speaker 2: Yeah, so the white parts would be closer, the dark 772 00:41:15,440 --> 00:41:18,840 Speaker 2: parts would appear more distant, and that creates the depth. 773 00:41:19,440 --> 00:41:22,120 Speaker 2: But then you still have to have that repeating pattern 774 00:41:22,200 --> 00:41:24,960 Speaker 2: laid out over the top of it, right, And I 775 00:41:24,960 --> 00:41:28,319 Speaker 2: mean that's basically you put that repeating pattern on top 776 00:41:28,760 --> 00:41:32,600 Speaker 2: and these vertical strips or rather a computer does, and 777 00:41:32,640 --> 00:41:35,640 Speaker 2: then that that program just translates the shades of those 778 00:41:35,680 --> 00:41:41,200 Speaker 2: pixels onto that depth map and via magic it all 779 00:41:41,200 --> 00:41:43,160 Speaker 2: comes together. Yeah, magic in program. It's neat. 780 00:41:43,160 --> 00:41:45,279 Speaker 1: And when I say sophisticated, I mean it. I saw 781 00:41:45,320 --> 00:41:47,440 Speaker 1: it in today. I'm really sad I didn't send it 782 00:41:47,480 --> 00:41:50,319 Speaker 1: to you. I meant to. But it is basically a 783 00:41:50,360 --> 00:41:53,360 Speaker 1: coral reef scene with different you can tell the different 784 00:41:53,400 --> 00:41:56,799 Speaker 1: kinds of fish, Like there's different clownfish closer in the foreground, 785 00:41:57,600 --> 00:42:00,440 Speaker 1: there's like triggerfish in the background, Like there's a middle 786 00:42:00,480 --> 00:42:03,280 Speaker 1: ground to the whole thing. Like that's how good they've gotten. 787 00:42:03,560 --> 00:42:05,839 Speaker 1: And like I was saying initially, when you see it 788 00:42:06,480 --> 00:42:09,080 Speaker 1: and you really see it, you can start looking around 789 00:42:09,160 --> 00:42:13,319 Speaker 1: inside the image. It's they it's just so amazing. You 790 00:42:13,320 --> 00:42:16,880 Speaker 1: just look up, like I guess, I think I searched 791 00:42:16,920 --> 00:42:21,920 Speaker 1: sophisticated stereograms or magic eye or something like that, and 792 00:42:21,960 --> 00:42:23,640 Speaker 1: it brought up some really good ones. 793 00:42:24,360 --> 00:42:27,239 Speaker 2: Yeah, it's uh. And what you mentioned earlier about like 794 00:42:28,200 --> 00:42:29,959 Speaker 2: the fact that you couldn't see him for so long, 795 00:42:30,480 --> 00:42:33,719 Speaker 2: you can only have this feeling once, which is not 796 00:42:34,000 --> 00:42:36,399 Speaker 2: ever being able to see one, to finally seeing your 797 00:42:36,400 --> 00:42:41,200 Speaker 2: first one. And when that picture jumps out from the 798 00:42:41,239 --> 00:42:45,600 Speaker 2: poster the very first time. It is like it's a thrill. 799 00:42:45,760 --> 00:42:48,399 Speaker 2: You're like, I finally got it. I see what you mean. 800 00:42:48,480 --> 00:42:51,920 Speaker 2: Because there's also this idea, which of course isn't true. 801 00:42:51,960 --> 00:42:54,720 Speaker 2: But you know, I remember when they first came around 802 00:42:54,840 --> 00:42:57,120 Speaker 2: that I thought it was like some people thought it 803 00:42:57,160 --> 00:43:01,080 Speaker 2: was like a snipe punt, right, Yeah, there is no picture, 804 00:43:01,120 --> 00:43:02,560 Speaker 2: and it's just a way you fool your friends and 805 00:43:02,719 --> 00:43:05,080 Speaker 2: staring at a thing for an hour. So when you 806 00:43:05,120 --> 00:43:07,239 Speaker 2: finally have it jump out and it's proven to you, 807 00:43:07,560 --> 00:43:09,440 Speaker 2: it's a pretty remarkable feeling. 808 00:43:09,560 --> 00:43:11,919 Speaker 1: It is, And there were a couple over the last 809 00:43:12,080 --> 00:43:13,680 Speaker 1: day or so where I was like, wait a minute, 810 00:43:13,760 --> 00:43:17,880 Speaker 1: is this Surely somebody out there has done that for fun. 811 00:43:17,960 --> 00:43:20,520 Speaker 1: But yeah, the whole thing wasn't just a big in joke. 812 00:43:20,560 --> 00:43:22,479 Speaker 1: I'm sure some people thought that for real. 813 00:43:23,200 --> 00:43:25,279 Speaker 2: Yeah. So the trick that you can use, there's a 814 00:43:25,320 --> 00:43:28,040 Speaker 2: few tricks. One is the one I mentioned earlier, is like, 815 00:43:28,920 --> 00:43:31,480 Speaker 2: if it's not a poster and it's a piece of paper, 816 00:43:31,600 --> 00:43:34,080 Speaker 2: you can hold hold it very close to your nose 817 00:43:34,800 --> 00:43:36,919 Speaker 2: where you can't even really focus on it, and very 818 00:43:37,600 --> 00:43:41,279 Speaker 2: slowly pull it away, but try and keep your try 819 00:43:41,320 --> 00:43:45,160 Speaker 2: not to focus on it still. Some many of them 820 00:43:45,160 --> 00:43:48,719 Speaker 2: will have two little objects, like two dots above the 821 00:43:48,760 --> 00:43:51,600 Speaker 2: whole thing, and they say, like, stare at those and 822 00:43:51,680 --> 00:43:53,319 Speaker 2: unFocus until you see three of them. 823 00:43:53,520 --> 00:43:54,359 Speaker 1: Wasn't able to do that. 824 00:43:55,160 --> 00:43:57,320 Speaker 2: I am not able to do that either, or maybe 825 00:43:57,480 --> 00:43:59,960 Speaker 2: I didn't try long enough. But I always just base 826 00:44:00,480 --> 00:44:03,040 Speaker 2: once I did the nose trick, and you have sort 827 00:44:03,080 --> 00:44:04,680 Speaker 2: of taught your eye, like I said, you can just 828 00:44:04,719 --> 00:44:07,480 Speaker 2: sort of get it by just sort of unfocusing in 829 00:44:07,520 --> 00:44:09,120 Speaker 2: the middle distance. 830 00:44:08,880 --> 00:44:11,279 Speaker 1: Right, Yeah, that's the way that I do it. Just 831 00:44:11,320 --> 00:44:13,719 Speaker 1: relax the eyes and let it. Yeah, you just gotta 832 00:44:13,760 --> 00:44:14,280 Speaker 1: be patient. 833 00:44:14,920 --> 00:44:15,680 Speaker 2: Gotta be patient. 834 00:44:16,880 --> 00:44:19,520 Speaker 1: I guess that's it. I think basically everybody should go 835 00:44:19,560 --> 00:44:23,280 Speaker 1: out and start looking at auto stereograms. Huh. 836 00:44:23,360 --> 00:44:26,320 Speaker 2: Yeah, they're not a joke. Nope, they're really neat images 837 00:44:26,360 --> 00:44:26,960 Speaker 2: are really there? 838 00:44:27,040 --> 00:44:30,479 Speaker 1: Yeah, the first time, like you were saying, you see 839 00:44:30,480 --> 00:44:34,080 Speaker 1: one pyrotechnics go off and the final countdown starts playing, 840 00:44:34,120 --> 00:44:35,880 Speaker 1: it's it's triumphant. 841 00:44:36,040 --> 00:44:38,160 Speaker 2: It's pretty well you always had the final catin I'm playing, 842 00:44:38,200 --> 00:44:39,160 Speaker 2: So that's probably what that was. 843 00:44:39,320 --> 00:44:41,839 Speaker 1: Yes, I do you got anything else? 844 00:44:42,640 --> 00:44:43,399 Speaker 2: I got nothing else? 845 00:44:43,440 --> 00:44:43,719 Speaker 1: All right? 846 00:44:43,760 --> 00:44:44,200 Speaker 2: Everybody? 847 00:44:44,200 --> 00:44:46,160 Speaker 1: That means, of course, it's time for listener mail. 848 00:44:48,680 --> 00:44:52,000 Speaker 2: So, my friend, I'm just gonna pick one at random. 849 00:44:52,040 --> 00:44:55,680 Speaker 2: And when I say randomly select, I mean randomly select 850 00:44:55,719 --> 00:44:58,760 Speaker 2: from the large pool of people who wrote in about 851 00:44:58,760 --> 00:44:59,239 Speaker 2: your mask. 852 00:45:01,280 --> 00:45:04,600 Speaker 1: Oh, we talk about this. I guess I did not 853 00:45:04,640 --> 00:45:05,200 Speaker 1: see this one. 854 00:45:06,000 --> 00:45:09,000 Speaker 2: If you remember from the short stuff episode recently on 855 00:45:09,080 --> 00:45:12,800 Speaker 2: Fahrenheit to Celsius conversion, I even commended you on the 856 00:45:12,800 --> 00:45:15,239 Speaker 2: show for being brave enough to try public math again 857 00:45:16,520 --> 00:45:19,160 Speaker 2: and apparently didn't get it right again. 858 00:45:20,280 --> 00:45:22,040 Speaker 1: Is it really a surprise to anybody though? 859 00:45:23,760 --> 00:45:25,480 Speaker 2: I don't know, is it? 860 00:45:25,640 --> 00:45:25,680 Speaker 3: No? 861 00:45:27,560 --> 00:45:32,080 Speaker 2: Let me see here. Let's go with Jake Eichenberger. Hey, guys, 862 00:45:32,200 --> 00:45:34,080 Speaker 2: I haven't laughed out loud to myself in a while, 863 00:45:34,120 --> 00:45:37,239 Speaker 2: but hearing Chuck compliments Josh Bravery with attempting live math 864 00:45:37,480 --> 00:45:39,719 Speaker 2: really hit the spot. I'm sure you get a lot 865 00:45:39,760 --> 00:45:43,560 Speaker 2: of emails. But for Celsius to Fahrenheit, you add the 866 00:45:43,560 --> 00:45:48,400 Speaker 2: thirty two after the multiplication, not before. And I always 867 00:45:48,400 --> 00:45:52,600 Speaker 2: treat one point eight as diprection nine fifths because five 868 00:45:52,719 --> 00:45:55,719 Speaker 2: is easy to deal with. So, for instance, for twenty one, 869 00:45:56,200 --> 00:45:58,680 Speaker 2: I would use twenty plus one because I use the 870 00:45:58,680 --> 00:46:00,840 Speaker 2: fact that twenty is easily to divide by five to 871 00:46:00,920 --> 00:46:05,920 Speaker 2: my advantage here. So jeez, now I don't understand any 872 00:46:06,000 --> 00:46:10,319 Speaker 2: of this, so blah blah blah math stuff. Now add 873 00:46:10,360 --> 00:46:13,360 Speaker 2: the thirty two they came up with thirty six, So 874 00:46:13,400 --> 00:46:16,319 Speaker 2: thirty six plus thirty two is sixty eight. And don't 875 00:46:16,320 --> 00:46:19,200 Speaker 2: forget about the plus one from earlier. Every one degree 876 00:46:19,239 --> 00:46:21,759 Speaker 2: celsius is one point eight, so sixty eight plus one 877 00:46:21,760 --> 00:46:24,759 Speaker 2: point eight would be sixty nine point eight as the 878 00:46:24,800 --> 00:46:26,160 Speaker 2: optimal butterfly temperature. 879 00:46:26,280 --> 00:46:29,120 Speaker 1: Yeah, I like my version better, even though it produces 880 00:46:29,120 --> 00:46:30,279 Speaker 1: incorrect results. 881 00:46:32,480 --> 00:46:34,160 Speaker 2: I mean I wouldn't even have tried it, So hats 882 00:46:34,160 --> 00:46:34,799 Speaker 2: off to you for that. 883 00:46:34,840 --> 00:46:37,040 Speaker 1: Thank you, thank you for still commending me, and thank 884 00:46:37,080 --> 00:46:39,040 Speaker 1: you to uh who. 885 00:46:38,680 --> 00:46:42,120 Speaker 2: That was just Jake, and let's say all the others. 886 00:46:41,960 --> 00:46:46,040 Speaker 1: Jake at all, I appreciate you guys for correcting me. 887 00:46:46,920 --> 00:46:51,160 Speaker 1: Thank you for that.
