We'll see you guys this August and September. 0:00:38.040 --> 0:00:46.960 Welcome to Stuff you Should Know, a production of iHeartRadio. 0:00:47.720 --> 0:00:50.120 Hey, and welcome to the podcast. I'm Josh, and there's 0:00:50.200 --> 0:00:52.720 Chuck and Jerry's here too. You can't see her, but 0:00:52.760 --> 0:00:56.840 you can if you relax your eyes lose focus, she 0:00:56.960 --> 0:01:00.120 may just pop right out at you and be like, hey, 0:01:00.120 --> 0:01:00.680 I'm Jerry. 0:01:00.720 --> 0:01:04.560 Could meet youa you thought I wasn't real? All you 0:01:04.640 --> 0:01:05.959 need her lazy eyes. 0:01:06.360 --> 0:01:09.240 That's well, no, actually it doesn't work if you have 0:01:09.440 --> 0:01:10.160 lazy eye. 0:01:10.360 --> 0:01:11.640 I know that's the opposite. 0:01:12.200 --> 0:01:13.119 We'll get to that later. 0:01:13.120 --> 0:01:15.160 I would love to see Jerry in in a Magic 0:01:15.200 --> 0:01:17.319 I poster popping out in my room. 0:01:18.160 --> 0:01:20.839 All right. You know, well, you know, it's actually become 0:01:20.959 --> 0:01:23.440 so easy to do. There's so many programs out there 0:01:23.480 --> 0:01:24.920 now that you do it. 0:01:25.000 --> 0:01:25.240 Huh. 0:01:25.280 --> 0:01:28.160 You could at the very least a more capable and 0:01:28.200 --> 0:01:30.520 skilled stuff you should know, listener, probably could. 0:01:30.959 --> 0:01:32.280 I'll just keep talking about it. 0:01:32.440 --> 0:01:32.800 There you go. 0:01:33.920 --> 0:01:34.880 That's what we're talking about. 0:01:34.880 --> 0:01:35.039 Though. 0:01:35.080 --> 0:01:38.840 If you are a person of a certain age, and 0:01:38.920 --> 0:01:42.560 you were either like a teenager or up probably in 0:01:42.560 --> 0:01:46.560 the nineteen nineties early nineteen nineties, yep, then you probably, 0:01:46.880 --> 0:01:50.720 at some point, much like Ethan Suppley in the movie 0:01:50.760 --> 0:01:55.120 Mall Rats, would stand somewhere in a shopping mall at 0:01:55.120 --> 0:01:58.240 a wooden kiosk, staring at a poster, waiting for that 0:01:58.880 --> 0:02:01.360 shark or that sale to come out from the background 0:02:01.360 --> 0:02:04.360 of that poster. Yeah, the hidden, the hidden trick. 0:02:04.960 --> 0:02:08.160 I tried it so many times, and I think maybe 0:02:08.480 --> 0:02:11.720 one out of fifty I was able. Oh yeah, I 0:02:11.800 --> 0:02:13.680 was not good at it, but I have to say Chuck. 0:02:14.000 --> 0:02:18.240 After researching it yesterday and today, my eye muscles have 0:02:18.400 --> 0:02:20.360 never been in better shape than they are right now. 0:02:20.639 --> 0:02:22.040 Did you try looking at them again? 0:02:22.200 --> 0:02:24.560 Yes, I've been popping and locking and like just I'll 0:02:24.600 --> 0:02:26.639 be like here, give it to me, bam, I'll see 0:02:26.639 --> 0:02:28.000 that one. Oh, let's see another one. 0:02:28.440 --> 0:02:30.760 Actually, I've got it, Yes, I did. 0:02:31.360 --> 0:02:34.040 I finally relax. I guess is what it comes down to. 0:02:34.639 --> 0:02:39.240 But I've gotten to the point where I can, once 0:02:39.280 --> 0:02:41.920 I see it, I don't have to keep that focus. 0:02:41.960 --> 0:02:46.760 I can actually look around inside the picture from like 0:02:46.800 --> 0:02:47.919 different angles and stuff. 0:02:47.960 --> 0:02:51.119 It's really cool. Yeah. I got to that point too, 0:02:52.320 --> 0:02:54.200 to where like at first I would do the trick 0:02:54.240 --> 0:02:56.880 where you like in the book version, where you would 0:02:56.880 --> 0:02:59.239 hold it very close to your face and slowly back 0:02:59.280 --> 0:03:02.240 it away, because as we'll see, that's one technique to 0:03:02.280 --> 0:03:05.000 see what the hidden picture. But then I got to 0:03:05.040 --> 0:03:07.680 where once you once you sort of contrain yourself, then 0:03:07.720 --> 0:03:09.400 you can just sort of look at it like you said, 0:03:09.440 --> 0:03:11.960 and you know, the little trick with your eyes, and 0:03:12.000 --> 0:03:14.160 then there's that polar bear or whatever. 0:03:14.400 --> 0:03:17.040 Yeah, but I should say it's been it's been brought 0:03:17.080 --> 0:03:19.560 to our attention. I guess ever since the Millie Vanilli 0:03:19.639 --> 0:03:23.040 episode that even like that kind of definition is not 0:03:23.160 --> 0:03:26.880 necessarily enough for some of our listeners. So I feel like, no, 0:03:27.000 --> 0:03:28.680 I think we should go a little further. If you've 0:03:28.720 --> 0:03:32.800 never seen a magic eye poster or you know generically 0:03:32.800 --> 0:03:38.480 called the stereogram, what we're talking about is a a strange, 0:03:38.640 --> 0:03:45.200 seemingly random pattern of different colors almost splattered across a poster, 0:03:46.080 --> 0:03:49.720 and that if you relax your eyes is a certain 0:03:49.760 --> 0:03:53.040 way so that you focus as if you're looking beyond. 0:03:52.720 --> 0:03:54.680 The poster, like right through it. Yeah. 0:03:54.760 --> 0:03:59.280 Hm, in some sort of magic scientific way that will explain, 0:03:59.600 --> 0:04:03.400 sort of a three dimensional image suddenly forms. You suddenly 0:04:03.480 --> 0:04:06.200 see a three D image that you cannot see if 0:04:06.240 --> 0:04:09.360 you're if you're not looking at it the right way. Yeah, 0:04:09.400 --> 0:04:12.680 when you do see it, there's it's almost inevitable you're 0:04:12.680 --> 0:04:16.880 gonna say wow, oh, gosh or something like that. It's 0:04:16.960 --> 0:04:19.160 thrilling every single time it is. 0:04:19.240 --> 0:04:21.640 It appears to kind of jump away from the rest 0:04:21.640 --> 0:04:25.800 of the image. But nice definition. But I think we 0:04:25.800 --> 0:04:29.120 should go back because there's kind of a long and 0:04:29.200 --> 0:04:32.120 winding road to how we eventually got to the early 0:04:32.200 --> 0:04:36.800 nineteen nineties with these magic eye posters. That were you know, 0:04:36.839 --> 0:04:38.599 they were real fad and we'll get to that. You know, 0:04:38.640 --> 0:04:40.640 they sold a lot of those things in a short 0:04:40.680 --> 0:04:43.640 amount of time. But it goes all the way back 0:04:43.760 --> 0:04:48.640 to the early scientists of the world trying to figure 0:04:48.680 --> 0:04:52.200 out how in the world when you have two eyeballs 0:04:52.880 --> 0:04:57.760 that are spaced about sixty something millimeters apart. You know, 0:04:57.800 --> 0:04:59.880 if they're spaced apart, they're gonna be seeing things f 0:05:00.000 --> 0:05:02.320 from a slightly different perspective. And how in the world 0:05:02.400 --> 0:05:04.320 do we do that and come up with like a 0:05:04.440 --> 0:05:06.679 solid focus on things? 0:05:07.000 --> 0:05:10.000 Yeah, I mean I had never really thought about it before, 0:05:10.040 --> 0:05:12.839 but binocular vision is what you're talking about. And yeah, 0:05:12.880 --> 0:05:14.960 by rights, we have two eyes, and like you said, 0:05:14.960 --> 0:05:17.360 they're separated by a certain amount of distance, So why 0:05:17.360 --> 0:05:19.600 don't we see two images of. 0:05:19.520 --> 0:05:22.800 The world, Yeah, very lightly from one another. Right. 0:05:23.640 --> 0:05:25.760 What It turns out that if we did do that, 0:05:25.960 --> 0:05:29.360 we probably wouldn't be able to see with depth perception. 0:05:29.520 --> 0:05:33.679 It's very crazy kind of It's called stereopsis is another 0:05:33.680 --> 0:05:37.960 word for depth perception, and it is in combining those 0:05:38.080 --> 0:05:41.440 two images that each eye gives the brain that we're 0:05:41.480 --> 0:05:44.520 able to see in one complete picture that has depth 0:05:44.800 --> 0:05:49.760 and richness and uh, maybe even a little kindness depending 0:05:49.800 --> 0:05:50.680 on what you're looking at. 0:05:51.240 --> 0:05:54.720 Yeah, and the brain does this immediately. It figures it 0:05:54.760 --> 0:05:57.240 out so fast you don't even know what's happening. But 0:05:57.320 --> 0:05:59.640 we can go all the way back to our friend Ptolemy, 0:05:59.720 --> 0:06:03.800 who talked about quite a bit. Yeah, second century Roman astronomer. 0:06:04.320 --> 0:06:06.520 And this is one of sort of the early ideas 0:06:06.520 --> 0:06:09.880 that were was put forward. And you know, they, as 0:06:10.040 --> 0:06:12.240 as with all things sort of science, they put forward 0:06:12.279 --> 0:06:14.840 some ideas that aren't quite right and they're refined over 0:06:14.839 --> 0:06:16.880 the years until they get to the reality of it. 0:06:17.120 --> 0:06:18.599 This is an ain't quite right one. 0:06:18.800 --> 0:06:21.160 Yeah, ain't quite right because told me he thought that 0:06:21.240 --> 0:06:25.240 your eyes sent out raise basically visual rays that hid 0:06:25.279 --> 0:06:29.800 an object, and when we're seeing something in focus, that 0:06:29.880 --> 0:06:32.360 means it's even it's kind of hard to explain how 0:06:32.360 --> 0:06:36.520 bad it is that the eyeball rays will converge on 0:06:36.640 --> 0:06:39.240 an object. And when they converge on that object, that's 0:06:39.279 --> 0:06:42.760 when you can see something in focus, basically, and if. 0:06:42.720 --> 0:06:44.880 They converge in it too much, they burn it to 0:06:44.960 --> 0:06:48.960 a cinder. Excellently, he had it, he picked up there's 0:06:48.960 --> 0:06:52.320 two things. He had it backwards. We're actually accepting rays 0:06:52.680 --> 0:06:55.640 rather than shooting him out, so he's kind of getting there. 0:06:56.400 --> 0:06:59.960 And then he noticed that our two eyes create an 0:07:00.800 --> 0:07:04.800 that's our focus. It can be wide narrow, depending on 0:07:04.839 --> 0:07:07.919 what we're looking at. If it's far away, the focus 0:07:08.000 --> 0:07:11.520 is going to be at a sharper angle. If it's closer, 0:07:11.520 --> 0:07:14.440 it's going to be at a wider angle. And he 0:07:14.560 --> 0:07:16.840 was onto something, but he didn't. He who wasn't able 0:07:16.840 --> 0:07:18.440 to really put two and two together, and then he 0:07:18.480 --> 0:07:19.600 died and that was it for him. 0:07:19.960 --> 0:07:23.120 Yeah, that's right. So up next, I guess we can 0:07:23.160 --> 0:07:28.160 flash forward to this Arab scholar name all has In 0:07:28.360 --> 0:07:29.120 is what I'm going to say. 0:07:29.160 --> 0:07:30.880 I think that's great, right. 0:07:32.040 --> 0:07:35.320 And he basically said, all right, what we have is 0:07:35.360 --> 0:07:39.240 an ability to sense this convergence of our eyes when 0:07:39.240 --> 0:07:43.400 they focus on an object. And what this is called basically, 0:07:43.560 --> 0:07:45.200 I don't know if he even said the word depth, 0:07:45.440 --> 0:07:47.680 but it helps us figure out how far something is, 0:07:47.840 --> 0:07:48.560 which is depth. 0:07:49.040 --> 0:07:51.800 Yes, And so his idea was that we could we 0:07:51.880 --> 0:07:55.000 had some sort of sense that we was so involuntary 0:07:55.040 --> 0:07:56.640 we weren't even aware of it, and that's how we 0:07:56.680 --> 0:08:00.160 knew its true. Yeah, for sure, but still not quite right. 0:08:00.200 --> 0:08:04.360 There about six hundred years later, Kepler and Descartes kind 0:08:04.360 --> 0:08:07.080 of picked up on something similar, and they said, rather 0:08:07.160 --> 0:08:11.360 than being able to sense the degree of convergence that 0:08:11.400 --> 0:08:15.680 our eyes are focusing, we actually can feel how our 0:08:15.720 --> 0:08:19.040 eyes are rotating at any given point, and that's how 0:08:19.080 --> 0:08:22.560 we know where our eyes are focused or not focused. 0:08:22.800 --> 0:08:27.040 Yeah, Descartes said, like googly eyes, you know exactly. 0:08:26.960 --> 0:08:30.320 And so like it was just wrong, wrong, wrong. Finally, 0:08:30.880 --> 0:08:35.080 in the eighteen thirties, an Englishman stepped up. His name 0:08:35.120 --> 0:08:39.360 was Sir Charles Wheatstone. Yeah, and he said, I've got this. 0:08:39.440 --> 0:08:43.760 Everybody check this out. I have invented an invention that 0:08:43.880 --> 0:08:48.280 will prove that my hypothesis of binocular vision providing us 0:08:48.440 --> 0:08:54.080 one single image with depth is actually from well take 0:08:54.080 --> 0:08:54.480 a chuck. 0:08:56.880 --> 0:08:59.280 Well, you know what's funny is in my notes I had. 0:08:59.400 --> 0:09:03.520 Wheatstone says, quote, I got this nice exactly what you said. 0:09:03.520 --> 0:09:04.400 It's simpatico. 0:09:04.760 --> 0:09:05.840 What were you setting me up for? 0:09:06.760 --> 0:09:07.240 I don't know. 0:09:08.240 --> 0:09:10.320 Well, he had an invention. Can I just describe that 0:09:10.400 --> 0:09:11.080 at least? Yeah? 0:09:11.080 --> 0:09:12.000 The stereoscope. 0:09:12.120 --> 0:09:16.000 Yeah, the stereoscope sat. The first version of this that 0:09:16.080 --> 0:09:19.520 he introduced sat on a table. There's a great picture. 0:09:19.600 --> 0:09:22.240 It turns out that Brian May of Queen is a 0:09:22.240 --> 0:09:29.000 big wheatstone slash three D stereogram binocular vision enthusiast, and 0:09:29.120 --> 0:09:31.400 so there's some cool pictures of him looking at this 0:09:31.559 --> 0:09:35.120 through this original stereoscope. So it sits on a desk 0:09:35.800 --> 0:09:39.320 and in the center you put your eyes up to 0:09:39.640 --> 0:09:42.000 you know, what looks like a little viewmaster or a 0:09:42.080 --> 0:09:46.240 VR headset basically, and it has these two angled mirrors, 0:09:46.240 --> 0:09:48.839 one for each eye. So when you look through it, 0:09:48.840 --> 0:09:51.439 it angles one eye out to the right and one 0:09:51.440 --> 0:09:54.800 eye out to the left, and in that peripheral vision 0:09:55.240 --> 0:09:58.440 on each side there's a little small wooden wall with 0:09:58.520 --> 0:10:01.480 a picture on each one. So one eye is looking 0:10:01.480 --> 0:10:03.839 at the left picture, the right eye is looking at 0:10:03.840 --> 0:10:06.520 the right picture, and you you know, it has two 0:10:06.520 --> 0:10:09.800 little thumbholes that you hold. It's very elegantly a little 0:10:09.800 --> 0:10:10.880 steampunk looking thing. 0:10:11.000 --> 0:10:11.800 It definitely is. 0:10:12.120 --> 0:10:17.079 And that was how he basically proved this, by having 0:10:17.120 --> 0:10:22.320 each eye look at two separate things, but they're both flat, flat, 0:10:22.640 --> 0:10:24.720 flat images of the same thing. Basically. 0:10:24.760 --> 0:10:25.760 That's really that's key. 0:10:25.880 --> 0:10:26.040 Right. 0:10:26.080 --> 0:10:28.960 So let's say you had an image of an apple cart. 0:10:29.559 --> 0:10:31.880 You have two pictures of that apple cart, and your 0:10:31.920 --> 0:10:35.000 eyes are seeing each one right, because there's that barrier 0:10:35.040 --> 0:10:38.160 in between your two eyes, so your eye is just 0:10:38.200 --> 0:10:40.760 seeing the left image, your right eye seeing just the 0:10:40.840 --> 0:10:41.400 right image. 0:10:41.480 --> 0:10:42.160 Right. Yes. 0:10:42.320 --> 0:10:44.960 The distinction here, Chuck, and this is where Wheatstone like 0:10:45.040 --> 0:10:49.079 really laid the foundation for understanding binocular vision is that 0:10:49.240 --> 0:10:52.760 each of those pictures has to be slightly different in perspective. 0:10:53.040 --> 0:10:53.440 That's right. 0:10:53.760 --> 0:10:57.320 So either there's a slightly different angle, or you took 0:10:57.360 --> 0:10:59.320 one picture and then moved a foot to the left 0:10:59.320 --> 0:11:01.320 and took the other picture, and those are what you're seeing. 0:11:01.760 --> 0:11:05.400 And what he showed is that the brain can sense 0:11:05.200 --> 0:11:09.560 those slight, slight differences in perspective and that's what it 0:11:09.720 --> 0:11:13.480 uses when it combines two images into one image in 0:11:13.520 --> 0:11:16.240 your field of view to give it depth. That's how 0:11:16.240 --> 0:11:21.600 it senses depth, those differences in perspective or angle that 0:11:21.720 --> 0:11:24.359 each eye is feeding the brain as an image. 0:11:24.640 --> 0:11:27.200 Yeah. And if you're thinking this sounds like the little 0:11:27.280 --> 0:11:29.560 viewmaster that you had when you were a kid, that's 0:11:29.600 --> 0:11:31.360 exactly what it is, same exact thing. 0:11:31.800 --> 0:11:34.400 Yeah, And the same way that like the computer went 0:11:34.440 --> 0:11:37.360 from like a room size thing to a PC to 0:11:37.520 --> 0:11:41.880 a laptop to our phone. This this stereoscope did the 0:11:41.920 --> 0:11:44.600 same thing. It was a big clunky thing, the steampunk version, 0:11:44.920 --> 0:11:48.160 and then it got increasingly smaller and easier to handle 0:11:48.559 --> 0:11:54.080 and more handy, although it was much less revolutionary than 0:11:54.160 --> 0:11:54.800 the computer. 0:11:55.320 --> 0:11:58.320 Yeah, they made it like, they made it more handheld. 0:11:58.400 --> 0:12:00.800 Those in particular, there was in the eighteen forties there 0:12:00.840 --> 0:12:04.040 was a Scottish physicist who will be pretty prominent in 0:12:04.080 --> 0:12:08.240 this whole story named David Brewster, Sir David Brewster, and 0:12:08.360 --> 0:12:11.040 he's the one that invented if you've ever seen one 0:12:11.040 --> 0:12:13.240 of these in a museum or something, sort of the 0:12:13.240 --> 0:12:17.840 early handheld version that looks like a little handheld steampunk 0:12:18.000 --> 0:12:19.840 VR headset basically. 0:12:19.600 --> 0:12:23.800 Yeah, like many binoculars with a slide yeah, coming out 0:12:23.800 --> 0:12:25.280 of it that you use for focus. 0:12:25.520 --> 0:12:26.960 Yeah, and you hold it up to your eyes and 0:12:27.000 --> 0:12:28.680 it blocks out the rest of the light and stuff. 0:12:30.080 --> 0:12:35.360 His more portable invention was coinciding with photography becoming more 0:12:35.400 --> 0:12:39.320 and more developed in sort of like proper photography, and 0:12:39.400 --> 0:12:42.920 so all of a sudden it was this popular thing, 0:12:43.080 --> 0:12:46.439 and this was sort of the first fad of the stereogram. 0:12:46.440 --> 0:12:47.800 There were a couple of big ones. It was one 0:12:47.800 --> 0:12:51.319 of the nineteen nineties and one in the mid nineteenth century. 0:12:52.040 --> 0:12:54.600 Queen Victoria went nuts for this thing in eighteen fifty 0:12:54.600 --> 0:12:58.640 one at the Great Exhibition at Crystal Palace, and all 0:12:58.640 --> 0:13:01.400 of a sudden, people just wanted these things to play 0:13:01.400 --> 0:13:03.040 with and look through and marvel at. Yeah. 0:13:03.160 --> 0:13:06.319 Right from the eighteen fifties to the nineteen thirties when 0:13:06.440 --> 0:13:10.440 radio finally came in and took over that there was 0:13:10.559 --> 0:13:13.920 basically not a parlor in the UK or America that 0:13:13.960 --> 0:13:17.160 didn't have one of these things. Like you just amused 0:13:17.200 --> 0:13:20.080 yourself with them. The fact that there were companies that 0:13:20.120 --> 0:13:24.640 were producing hundreds of thousands or millions of different stereoscopic 0:13:24.720 --> 0:13:27.480 images for you to look at. I mean, you could 0:13:27.480 --> 0:13:30.920 just spend endless hours of entertainment looking at one thing 0:13:31.000 --> 0:13:35.840 or another. And they would take images of like scenic landmarks. 0:13:36.040 --> 0:13:42.280 Sure supposedly stereoscopic images of like Yellowstone. I think the 0:13:42.360 --> 0:13:48.720 Yellowstone Area actually convinced congressmen back east that there actually 0:13:48.880 --> 0:13:53.920 was an amazing wilderness out there that should that's worth preserved. Yeah, exactly. 0:13:53.920 --> 0:13:56.040 It really made it pop. In other words, they also 0:13:56.120 --> 0:14:00.599 very quickly started making porn with it. Everything that you 0:14:00.640 --> 0:14:03.240 would imagine people doing when they figured out how to 0:14:03.280 --> 0:14:06.839 make pictures that really stand out with depth, Yeah you did. 0:14:07.120 --> 0:14:09.640 They were like, these are fantastic, but what's better than 0:14:09.640 --> 0:14:16.800 a landscape? Ladies' ankles? Pretty much the original The original 0:14:16.880 --> 0:14:20.400 piece of equipment used to make these were stereo cameras, 0:14:20.400 --> 0:14:23.640 and they were these cameras with two lenses that kind 0:14:23.640 --> 0:14:25.480 of mimic the eyes. They're said about eye with the 0:14:25.520 --> 0:14:28.840 part and those were around for a while, and there 0:14:28.880 --> 0:14:32.360 are still enthusiasts that own stereo cameras, as we'll see 0:14:32.400 --> 0:14:34.080 in a little bit. That kind of figures into how 0:14:34.080 --> 0:14:38.080 they became popular in the nineties. But in the United States, 0:14:38.160 --> 0:14:43.040 while all this was going on, American surgeon Oliver Wendelholmes 0:14:43.120 --> 0:14:48.360 senior papa of Oliver Wendelholmes Junior of the spring Court fame, 0:14:49.560 --> 0:14:52.760 he's invented one in the United States and he's like, 0:14:52.800 --> 0:14:54.680 you know what, this thing's so great, I'm not even 0:14:54.680 --> 0:14:57.200 going to patent it. I want all kind of companies 0:14:57.240 --> 0:14:59.880 to make these, and I want these spread far and wide. 0:15:00.440 --> 0:15:02.120 I guess he was a surgeon, so he wouldn't hurt 0:15:02.200 --> 0:15:05.520 her anything, right, and people, I think he's the one 0:15:05.520 --> 0:15:10.440 that coined the term stereograph, and then the word stereogram 0:15:10.520 --> 0:15:12.840 kind of became the go to for these images. 0:15:12.920 --> 0:15:15.600 Yeah, everybody's like close, we're gonna switch it up just 0:15:15.640 --> 0:15:18.560 a little bit. And still today, if you're an enthusiast 0:15:18.640 --> 0:15:23.720 into stereoscopic photography, the stereogram is usually the term that 0:15:23.760 --> 0:15:24.240 you'd use. 0:15:25.000 --> 0:15:28.240 All right, I think that's a robust fifteen minutes. 0:15:28.480 --> 0:15:33.960 Yeah, all of the nineteenth century stereogram viewers say bully, bully, bully. 0:15:34.400 --> 0:15:37.880 That's right, bully in three D. So we'll be back 0:15:37.920 --> 0:15:40.560 to talk about the next development, which was the auto 0:15:40.640 --> 0:15:42.160 stereogram right after this. 0:15:42.720 --> 0:15:46.160 If you want to know then you're in luck. Just 0:15:46.360 --> 0:15:53.120 listen to joshcher seffus no. 0:15:55.560 --> 0:16:09.720 Stuffus, no, all right, check. Now we finally get to 0:16:09.760 --> 0:16:14.440 this stuff where I'm fascinated. Yeah, just riveted, right because 0:16:14.600 --> 0:16:20.560 it's it's enough that our friends Wheatstone and Brewster contributed 0:16:20.920 --> 0:16:24.960 the foundation to our understanding of binocular vision. But along 0:16:25.040 --> 0:16:27.040 came in I think the nineteen fifties. 0:16:27.240 --> 0:16:29.360 Boy, that sounds like a craft cocktail bar, isn't it. 0:16:30.280 --> 0:16:34.080 Bruce Wheatstone Andrews like, you have to have the armband 0:16:34.160 --> 0:16:35.480 or else you can't get employed. 0:16:35.480 --> 0:16:37.280 There. I just got really thirsty. Sorry, go ahead. 0:16:37.760 --> 0:16:43.080 There was a scientist a neuroscientist named Bella. ULA's had 0:16:43.160 --> 0:16:46.200 tip to Chuck for that one who ran the Sensory 0:16:46.240 --> 0:16:50.880 and Perceptual Processes department at AT and T Bell Labs. Again, 0:16:51.040 --> 0:16:55.440 I think, I said in the fifties, and ULA's was, 0:16:55.880 --> 0:17:00.280 I guess kind of focused on visual perception and figure 0:17:00.360 --> 0:17:02.760 something out. They just like just in the same way 0:17:02.800 --> 0:17:06.879 that that Wheatstone's invention kind of led to this neat 0:17:07.000 --> 0:17:07.600 in this. 0:17:07.600 --> 0:17:09.359 Neat party toy toy. 0:17:09.600 --> 0:17:13.919 Yeah, ULA's invention kind of did the same thing, but 0:17:14.080 --> 0:17:17.280 neither one of them were trying to create an amusement. 0:17:17.359 --> 0:17:20.359 They were they were creating a way to prove a 0:17:20.440 --> 0:17:23.680 hypothesis that they were interested in. And what he did 0:17:24.040 --> 0:17:26.439 was come up with the random dot stereogram. 0:17:27.080 --> 0:17:31.600 Yeah, so this is uh, he basically start by let's 0:17:31.640 --> 0:17:33.199 say you have like a square or something that you 0:17:33.240 --> 0:17:37.320 fill in randomly with black dots, and then within that 0:17:37.440 --> 0:17:40.959 square you picked a part of it and decide on 0:17:41.040 --> 0:17:44.840 like maybe a shape or something. So within that that square, 0:17:45.119 --> 0:17:47.720 you'll say, all right, well, I'm gonna select a circle 0:17:47.760 --> 0:17:50.200 within that, like maybe right in the middle, and I'm 0:17:50.200 --> 0:17:53.199 going to create a second square that's just like the first, 0:17:53.720 --> 0:17:57.119 except that circle in the center that I've selected is 0:17:57.240 --> 0:17:59.400 just going to be shifted just a little bit, kind 0:17:59.400 --> 0:18:02.119 of like we were talking about, that slight, slight difference 0:18:02.160 --> 0:18:05.040 of perspective. Yeah, and then when you put these two 0:18:05.080 --> 0:18:08.160 squares side by side, and when you look at these 0:18:08.200 --> 0:18:11.120 two squares, you can look at it through a stereoscope 0:18:11.160 --> 0:18:13.439 if you have one. But the key here is is 0:18:13.480 --> 0:18:15.639 that he would prove that, like, hey, you can just 0:18:15.680 --> 0:18:18.240 do this with your naked eye if you learn the 0:18:18.600 --> 0:18:20.879 trick that people will be trying to figure out, you know, 0:18:21.000 --> 0:18:24.480 up until twenty twenty three with future podcaster Josh Clark, 0:18:25.080 --> 0:18:28.600 where you unFocus your eyes and then those circles appear 0:18:28.680 --> 0:18:30.280 to sort of separate from the background. 0:18:30.480 --> 0:18:34.840 Yeah, and so those two separate images, you still see them, 0:18:35.000 --> 0:18:37.000 but what they do is combine to make a third 0:18:37.040 --> 0:18:39.640 image in the center, and that's the one that has 0:18:39.720 --> 0:18:42.560 the say, the circle popping out of it, right. 0:18:42.680 --> 0:18:43.240 Yeah. 0:18:43.280 --> 0:18:47.280 And Youlss obviously created the foundation for magic eye posters 0:18:47.359 --> 0:18:50.679 with that. But what he did more than anything was 0:18:50.880 --> 0:18:55.280 show that what our brain does when it takes in 0:18:55.320 --> 0:18:59.199 those two separate images and slightly different perspectives because their 0:18:59.200 --> 0:19:05.040 eyes are separated just ever so slightly, it compares basically 0:19:05.119 --> 0:19:10.320 pixel for pixel each of the each of the images 0:19:10.359 --> 0:19:13.959 that the eye send it and matches it up, and 0:19:14.000 --> 0:19:17.360 then when it finds parts that don't quite match up, 0:19:17.840 --> 0:19:22.440 it uses that to create the illusion of depth. And 0:19:22.520 --> 0:19:27.520 that's what his random dot stereogram showed that what your 0:19:27.560 --> 0:19:30.640 eye is doing is taking those two those two pictures 0:19:30.800 --> 0:19:34.239 and matching up every single random dot in there and 0:19:34.280 --> 0:19:38.720 then noticing all this is in a nanosecond, noticing what 0:19:39.359 --> 0:19:41.840 it doesn't match up, and then that's that circle that 0:19:41.960 --> 0:19:45.320 pops out. And then the way that he proved it 0:19:45.359 --> 0:19:49.719 is because those two different pictures form a single image 0:19:49.720 --> 0:19:54.000 in the center. Right, Yeah, So if you weren't looking 0:19:54.040 --> 0:19:56.199 at two pictures, you were just using two eyes at 0:19:56.240 --> 0:20:00.159 one picture, then that effect would still be produced. And 0:20:00.200 --> 0:20:02.200 it really just kind of laid the foundation in showing 0:20:02.600 --> 0:20:07.000 just exactly how our brain makes binocular vision into depth perception. 0:20:07.760 --> 0:20:12.480 Right, So we're inching closer to the nineties and that 0:20:12.880 --> 0:20:17.840 singular poster or coffee table book image that we all knew, 0:20:18.640 --> 0:20:21.280 but it came to us in the nineteen seventies thanks 0:20:21.320 --> 0:20:25.920 to a student of u Less's named Christopher Tyler, who 0:20:25.960 --> 0:20:30.080 was a neuroscientist and he basically said, you know what, 0:20:30.600 --> 0:20:33.880 we don't even need the two pictures. Everybody like you're 0:20:33.880 --> 0:20:36.880 doing pretty good, but what if, like how mind blowing 0:20:36.920 --> 0:20:38.960 would it be if we could do this all from 0:20:39.000 --> 0:20:43.080 a single image. He called it the auto stereogram and 0:20:43.359 --> 0:20:46.320 basically made it to where it's sort of like this, 0:20:47.520 --> 0:20:50.280 like staring at a wallpaper. And in fact, I think 0:20:50.560 --> 0:20:53.560 was he the one here? Then it was Brewster who 0:20:53.880 --> 0:20:56.280 stared at wallpaper, and that's how they figured that out. 0:20:56.320 --> 0:20:59.520 He was an odd duck, which is interesting. But Tyler 0:20:59.560 --> 0:21:03.160 got together with a programmer named Maureen Clark and said, well, 0:21:03.200 --> 0:21:05.680 we can probably figure this out with math, So that 0:21:05.720 --> 0:21:10.320 they created an algorithm that could insert these images into 0:21:10.359 --> 0:21:13.840 what looks like just almost like white noise on paper. 0:21:13.960 --> 0:21:15.679 Yeah, And so they did away with all the crud, 0:21:15.760 --> 0:21:19.639 those extra two images that still remain when that third 0:21:19.640 --> 0:21:22.600 when they come together and form that illusory third image 0:21:22.600 --> 0:21:25.479 in the middle. Yeah, so that you just see something 0:21:25.520 --> 0:21:27.840 as you normally would see it. But if you adjust 0:21:27.880 --> 0:21:30.000 your eyes just the right way, then that three D 0:21:30.040 --> 0:21:31.719 image is going to come out. And now we finally 0:21:31.800 --> 0:21:36.080 arrive in the nineteen seventies at the auto stereogram is 0:21:36.119 --> 0:21:40.440 what they called it, which became better known eventually as 0:21:40.480 --> 0:21:41.560 the Magic Eye poster. 0:21:42.520 --> 0:21:45.480 Right, So, if you're listening to this and you're thinking, 0:21:45.840 --> 0:21:48.560 all right, guys, this is the nineteen seventies. You keep 0:21:48.560 --> 0:21:52.080 talking about the grunge era. How did we get from 0:21:52.080 --> 0:21:54.840 the nineteen seventies to the grunge era or why didn't 0:21:54.840 --> 0:21:58.320 we get there quicker? Basically? And one of the reasons 0:21:58.440 --> 0:22:02.280 is this guy named Tom Shay. He's from Connecticut. He 0:22:02.400 --> 0:22:04.639 has sort of a sounds like, sort of a hippie 0:22:04.640 --> 0:22:08.720 dippy backstory through the nineteen sixties, working all kinds of 0:22:08.720 --> 0:22:11.960 crazy jobs, but was like a super bright guy, a 0:22:12.160 --> 0:22:16.679 mathematician and musician. Eventually got you know, real grown up 0:22:16.720 --> 0:22:20.920 type jobs like helped NASA make their navigation systems, working 0:22:20.920 --> 0:22:24.680 with a company called Intermetrics, and in the early nineties 0:22:24.840 --> 0:22:30.520 landed at a British tech company called Pentica. And this 0:22:30.600 --> 0:22:33.000 thing all came together really in the in the thing 0:22:33.000 --> 0:22:34.800 that we all knew in love in the nineties because 0:22:34.800 --> 0:22:39.120 of advertising. They had a product Pentica did called the 0:22:39.160 --> 0:22:43.879 mime Capital mim in Circuit Emulator, and they were Boushet 0:22:44.000 --> 0:22:47.399 was tasked to designing an ad for this thing, and 0:22:47.480 --> 0:22:49.560 so he said, Hey, let's put a real mime in 0:22:49.600 --> 0:22:53.320 this advertisement. It's all very serendipitous because it really is 0:22:53.440 --> 0:22:56.399 this mime that they hired. It's either Lab or labby 0:22:56.520 --> 0:23:00.520 Labb shows up on set and it turns out that 0:23:00.760 --> 0:23:05.879 Lab was one of those stereo photography enthusiasts that still 0:23:05.920 --> 0:23:10.719 had those you know, dual lensed stereo cameras. He happened 0:23:10.720 --> 0:23:13.080 to bring this thing in on the set and Bashet 0:23:13.400 --> 0:23:18.000 was like, OMG, what is that thing and just was like, 0:23:18.240 --> 0:23:20.199 sounds like it was just instantly sort of taken with 0:23:20.240 --> 0:23:20.760 his idea. 0:23:20.960 --> 0:23:23.800 Yeah, he said it was the most compelling optical illusion 0:23:23.920 --> 0:23:24.879 I'd ever seen. 0:23:25.320 --> 0:23:26.760 There you haven't in his own words. 0:23:27.000 --> 0:23:30.119 So what he did he said, Okay, I really appreciate 0:23:30.160 --> 0:23:31.959 your help here, so I'm going to keep going with 0:23:32.000 --> 0:23:34.320 this mime ad, but I'm also going to try to 0:23:34.359 --> 0:23:38.280 make another ad using one of these auto stereograms, and 0:23:38.320 --> 0:23:41.560 he did. He made one that had the hidden message 0:23:41.680 --> 0:23:45.720 M seven hundred, which was a version of their in 0:23:45.840 --> 0:23:48.040 circuit emulator that his company made. 0:23:48.359 --> 0:23:50.080 Which who knows what that is. I even tried to 0:23:50.080 --> 0:23:50.640 figure it out. 0:23:51.040 --> 0:23:54.439 So the best I could see is that it's a like, 0:23:54.720 --> 0:23:58.680 rather than using your computer to figure out if a 0:23:58.720 --> 0:24:03.720 circuit like a microprocess or a circuit board works. This 0:24:03.800 --> 0:24:08.600 thing emulates either your computer or a circuit board so 0:24:08.640 --> 0:24:11.960 that you can find individual bugs and fix them. That's 0:24:12.000 --> 0:24:14.879 the best I could come up with. It's still very confusing, 0:24:14.920 --> 0:24:16.399 but that's yeah, that's that. 0:24:16.880 --> 0:24:19.520 And just so as a listener, you're not confused. That 0:24:19.560 --> 0:24:21.600 has nothing to do with what happened. It was just 0:24:21.640 --> 0:24:25.359 a product. It could have been a widget or whatever, definitely, 0:24:26.240 --> 0:24:28.960 but the idea was it was another ad that he 0:24:29.040 --> 0:24:33.359 actually used the technology to make a autostereogram for this ad. 0:24:33.520 --> 0:24:38.040 And this ad was so it made such an impression 0:24:38.040 --> 0:24:40.720 on people that it made it out of the pages 0:24:40.840 --> 0:24:48.080 of Embedded Systems Engineering Magazine into something of like the 0:24:48.160 --> 0:24:51.560 general corporate culture. And all of a sudden, at his 0:24:51.680 --> 0:24:57.480 desk at Pentica, but Shea starts getting faxes from people saying, Hey, 0:24:57.760 --> 0:25:00.760 can you make me and my company one of those 0:25:00.920 --> 0:25:04.560 really neat ads that you made? And he ended up 0:25:04.640 --> 0:25:08.560 kind of creating like a little mini side job for himself, 0:25:09.880 --> 0:25:14.320 creating custom auto stereograms for people who faxed him and 0:25:14.359 --> 0:25:14.919 asked for him. 0:25:15.520 --> 0:25:19.080 Yeah, he was no artist, though, so very smartly. In 0:25:19.160 --> 0:25:21.640 nineteen ninety one, he hooked up with a woman named 0:25:21.640 --> 0:25:26.000 Sherry Smith, who was an artist, a freelancer, and I 0:25:26.000 --> 0:25:30.200 think was also a computer graphics person, and so he said, 0:25:30.359 --> 0:25:32.720 you're perfect. You're an artist and you know computer graphics, 0:25:33.040 --> 0:25:35.639 so you can kick this thing up a notch and 0:25:36.119 --> 0:25:38.520 basically make images that are a little more interesting to 0:25:38.520 --> 0:25:41.800 look at. But it was still sort of an advertising 0:25:41.800 --> 0:25:45.040 thing because they made one for American Airlines for their 0:25:45.080 --> 0:25:49.080 in flight magazine that was really popular and apparently for 0:25:49.160 --> 0:25:51.639 a while at least they would give away a bottle 0:25:51.640 --> 0:25:54.720 of champagne. I would think a glass, but I guess 0:25:54.720 --> 0:25:57.080 a bottle of champagne to the first person on the 0:25:57.119 --> 0:25:59.639 flight who could find the image and say what it was. 0:26:00.119 --> 0:26:03.760 Of course it was an airplane. But after the American 0:26:03.800 --> 0:26:07.040 Airlines ad thing, Boshe was like, wait a minute, like 0:26:07.080 --> 0:26:09.480 people are going nuts for this in ads. But I think, 0:26:09.600 --> 0:26:11.320 like people are going so crazy for this, I think 0:26:11.359 --> 0:26:13.720 we could just sell these somehow, right. 0:26:13.880 --> 0:26:17.439 Take his job for making these four other companies and 0:26:17.520 --> 0:26:19.800 just make them and sell them directly to the public. 0:26:20.040 --> 0:26:22.840 And he actually started out doing mail order. He was 0:26:22.960 --> 0:26:25.760 he realized he was onto something because he started doing 0:26:25.800 --> 0:26:28.520 mail order in order to try to kick off a 0:26:28.560 --> 0:26:31.600 fad that he could then go and license to other 0:26:31.680 --> 0:26:34.800 people or partner with a big company and make himself 0:26:34.840 --> 0:26:38.040 that much more desirable. He really approached this in a 0:26:38.080 --> 0:26:38.880 smart way. 0:26:39.040 --> 0:26:41.880 A kickstarter of the time probably was mail order exactly. 0:26:41.960 --> 0:26:44.480 Yeah, that's a really great analogy. And he created a 0:26:44.640 --> 0:26:47.280 company or either he created it or he already had 0:26:47.320 --> 0:26:52.240 it and repurposed it. N period e period thing enterprises. 0:26:52.560 --> 0:26:57.320 Very clever, very very clever anything. Yeah, and he dieted everyone. 0:26:57.440 --> 0:27:01.359 He just one hundred percent, just to make sure instead 0:27:01.359 --> 0:27:05.040 of N period e period what you're really saying is 0:27:05.160 --> 0:27:06.160 a and y. 0:27:06.840 --> 0:27:09.280 Thing anything anything. 0:27:09.320 --> 0:27:13.320 We're anything enterprises, right, so anything N period e period 0:27:13.440 --> 0:27:18.199 Thing Enterprises partnered with a Japanese company called Tenyoh and 0:27:18.280 --> 0:27:21.919 Tenya was a magic trick maker. They still are as 0:27:21.960 --> 0:27:26.520 far as I can tell, and they said, this actually 0:27:27.160 --> 0:27:30.000 is amazing, and we think our friends in Japan are 0:27:30.000 --> 0:27:31.800 going to go crazy for it, and they licensed it 0:27:31.880 --> 0:27:35.879 and started publishing books based on the Magic Eye what 0:27:35.920 --> 0:27:38.280 would come to be No Magic Eye as Magic Eye, 0:27:38.320 --> 0:27:40.400 And apparently it was the ten Year company that said, 0:27:40.600 --> 0:27:42.520 let's call it Magic Eye because the name you have 0:27:42.640 --> 0:27:43.640 for it is stupid. 0:27:44.359 --> 0:27:48.040 I disagree. They called it Magic Eye because, like you said, 0:27:48.040 --> 0:27:49.680 they were a magic trick company and had a line 0:27:49.720 --> 0:27:53.199 of magic this, magic that. But I think Boushat's original 0:27:53.320 --> 0:28:00.000 name stereos hyphen or I guess Kama the Amazing Thing 0:28:00.400 --> 0:28:03.280 gays toys, So you have to spell it out well, 0:28:03.400 --> 0:28:06.600 S T A R E stare stereos. I kind of 0:28:06.640 --> 0:28:09.359 like that. I think it's catchy. You forgot the hyphens, No, 0:28:09.680 --> 0:28:12.560 S T A R E hyphen e hyphens right. 0:28:13.080 --> 0:28:16.440 You know who would love this bishet? Guys Jonathan Strickland. Yeah, 0:28:16.560 --> 0:28:19.280 he's a puny type, so I think Strickland would be like, 0:28:19.359 --> 0:28:20.879 You're my kind of guy, for sure. 0:28:21.680 --> 0:28:24.280 I think you should tell everyone, though, the great great 0:28:24.400 --> 0:28:28.399 name of or rather the great translated name of the 0:28:28.880 --> 0:28:31.200 first book that they put out in Japan of these. 0:28:31.160 --> 0:28:34.600 So thank you for that. It's called Muru Muru Mega 0:28:35.080 --> 0:28:37.520 yaka Nadu MAGICI. 0:28:37.760 --> 0:28:40.040 Which means translated. 0:28:39.560 --> 0:28:42.200 Your eyesight gets better and better in a very short 0:28:42.280 --> 0:28:44.280 rate of time. Colon MAGICI. 0:28:45.440 --> 0:28:48.400 That's so good, and it was a hit. 0:28:48.480 --> 0:28:50.960 Apparently it was the best seller. Very quickly I think 0:28:50.960 --> 0:28:53.560 they started I read they started selling them on street 0:28:53.600 --> 0:28:57.120 corners and then very quickly after that, the first print, 0:28:57.520 --> 0:28:59.880 the first printing ran out and they they made an 0:29:00.280 --> 0:29:01.960 huge run and that sold out, and it was just 0:29:02.080 --> 0:29:04.920 a hit in Japan. And it's interesting it went from 0:29:05.120 --> 0:29:09.160 America to Japan and then back to America where it 0:29:09.240 --> 0:29:10.360 really kind of blew up. 0:29:11.200 --> 0:29:14.160 Yeah, I guess Bashad didn't have from what I could tell, 0:29:15.120 --> 0:29:17.960 he was partnered in Japan, but I guess still had 0:29:18.000 --> 0:29:21.680 the rights to do it in the United States, even though, 0:29:21.680 --> 0:29:24.800 as we'll see, like he didn't own this idea like 0:29:24.840 --> 0:29:27.520 no one did, because other people came along later. It 0:29:27.640 --> 0:29:30.320 was it wasn't like a specific technology you could patent 0:29:30.440 --> 0:29:33.640 or anything. But he was the first person in the US, 0:29:33.640 --> 0:29:37.360 it looks like, to bring it over here and partner 0:29:37.440 --> 0:29:41.200 with a guy named Bob Slitski who was a former 0:29:41.560 --> 0:29:45.800 colleague at Pentica. And it sounds like Slitski was a 0:29:45.800 --> 0:29:49.920 guy who just made a more robust computer program to 0:29:50.040 --> 0:29:52.080 automate the stuff, to make it easier to come up 0:29:52.080 --> 0:29:55.920 with different images, and then also colorize it so they 0:29:55.960 --> 0:29:58.640 were previously black and white, and all of a sudden 0:29:58.880 --> 0:30:03.080 you could do these things which made them look sharper. Evidently, 0:30:04.240 --> 0:30:07.440 they hooked up with a licensing agent named Mark Gregorrek 0:30:07.960 --> 0:30:10.680 who said, hey, this thing like we could license the 0:30:10.720 --> 0:30:12.280 cred out of this person. Thing we had to do 0:30:12.400 --> 0:30:14.600 was get in a book, which they did in nineteen 0:30:14.640 --> 0:30:17.920 ninety three, and that was that very first what ended 0:30:17.960 --> 0:30:20.920 up being super popular Magic eyebook. 0:30:21.440 --> 0:30:23.680 Yeah. I mean, think about how Saren dippis it is, 0:30:23.720 --> 0:30:26.120 starting with Ron lab and then all of the people 0:30:26.200 --> 0:30:28.680 he met along the way who ended up making this 0:30:28.840 --> 0:30:32.080 the fad that it became. He really lucked out. He 0:30:32.120 --> 0:30:37.320 fell backwards into something really interesting. But they released a 0:30:37.360 --> 0:30:39.760 bunch of books. But while the first Magic Eyebook in 0:30:39.760 --> 0:30:42.680 the United States was still fresh on the best seller list, 0:30:42.760 --> 0:30:44.880 they released a second one and that quickly joined the 0:30:44.880 --> 0:30:47.800 first one on the best seller list. America just went 0:30:47.920 --> 0:30:48.920 nuts for these things. 0:30:49.040 --> 0:30:49.320 Yeah. 0:30:49.440 --> 0:30:51.600 One reason it went nuts is because there was a 0:30:51.640 --> 0:30:56.480 certain measure of superiority that you could hold people who. 0:30:56.320 --> 0:30:58.000 Couldn't do it, like you'd see it. 0:30:58.040 --> 0:31:01.600 There were people out there, including me, you just couldn't 0:31:02.120 --> 0:31:04.200 do it, and you just get so mad and frustrated, 0:31:04.200 --> 0:31:06.360 and people who could do it found that really satisfying. 0:31:06.400 --> 0:31:07.480 I've always suspected. 0:31:07.960 --> 0:31:10.239 Yeah, it took me a while. It wasn't like I 0:31:10.320 --> 0:31:13.480 instantaneously got it. But I eventually did. And that was 0:31:13.600 --> 0:31:15.320 kind of the joke in Mall Rats. I don't know 0:31:15.320 --> 0:31:18.440 if you ever saw that movie. I didn't, but it was, 0:31:18.880 --> 0:31:22.040 you know, the Kevin Smith movie, I guess, right after 0:31:22.080 --> 0:31:25.320 Clerk's and Ethan Suppley, like I said, would stare and 0:31:25.360 --> 0:31:27.600 stare at it, and people were making fun of him, 0:31:27.640 --> 0:31:30.440 and like there's one scene like these two little kids 0:31:30.480 --> 0:31:32.840 came up and like got it right away, and he 0:31:32.960 --> 0:31:34.280 just gets more and more frustrated. 0:31:34.320 --> 0:31:35.720 So he's for that. 0:31:36.000 --> 0:31:37.840 Yeah, that's sort of playing into what you were talking 0:31:37.880 --> 0:31:39.640 about with just like feeling like a dummy if you 0:31:39.640 --> 0:31:40.160 couldn't get it. 0:31:40.240 --> 0:31:42.800 Yeah, and that definitely was a thing. I've read, you 0:31:42.840 --> 0:31:45.920 know a number of like kind of retrospectives about it, 0:31:46.040 --> 0:31:48.280 and most of them were from people who couldn't get it, 0:31:48.320 --> 0:31:51.720 and they still seemed slightly bitter, but they still can't 0:31:51.720 --> 0:31:54.560 get it, you know, thirty years on or whatever. But 0:31:55.360 --> 0:31:58.320 it was. It was enormous, not just at mal kiosks, 0:31:58.360 --> 0:32:01.600 but in books. There is a comic strip that's still 0:32:01.600 --> 0:32:04.320 around that you can license through UPI if you want. 0:32:05.280 --> 0:32:09.400 It showed up on Honeynut Cheerios boxes. There were postcards, 0:32:09.680 --> 0:32:11.880 other companies came a call in and said, hey, we 0:32:11.920 --> 0:32:13.800 want you to make some of these for us, like Disney. 0:32:14.000 --> 0:32:17.440 I think CBS had them do something for like one 0:32:17.480 --> 0:32:22.000 of their internal sales booklets. It just started showing up everywhere, 0:32:22.360 --> 0:32:26.120 and I think the cream of the crop of like 0:32:26.400 --> 0:32:29.680 additional stuff that came out of this was a book 0:32:29.760 --> 0:32:33.680 that Boshet put together, a magic eyebook for Christmas called 0:32:33.720 --> 0:32:36.120 do you See What I See? 0:32:37.120 --> 0:32:39.080 That just presses Yeah, that's good. 0:32:39.120 --> 0:32:41.720 I couldn't find one. I found a Christmas themed one, 0:32:41.760 --> 0:32:43.080 but I don't think it was from the do you 0:32:43.160 --> 0:32:43.880 See What I See? 0:32:43.880 --> 0:32:48.120 Book? That's disappointing. It was a little bit so Bishey 0:32:48.560 --> 0:32:54.080 basically said in nineteen ninety four, in one year he 0:32:54.280 --> 0:32:57.680 estimates that they raked in between two hundred and a 0:32:57.720 --> 0:33:01.440 quarter of a million bucks or sorry, quarter of a 0:33:01.480 --> 0:33:04.440 billion billion dollars and hundred and fifty million. 0:33:04.520 --> 0:33:05.800 Yeah, and that was I think the peak here in 0:33:05.840 --> 0:33:09.200 ninety three or ninety four was it was huge. 0:33:09.480 --> 0:33:15.160 All right, So Bashe is going strong. Early nineties, Like 0:33:15.200 --> 0:33:18.560 I said, no one owned this idea. It's not a 0:33:18.560 --> 0:33:22.120 particular technology. So people started jumping on board and doing 0:33:22.160 --> 0:33:25.240 their own and the main standout to me, I think 0:33:25.360 --> 0:33:28.360 is are the guys who if you saw them at 0:33:28.360 --> 0:33:31.800 the mall kiosks, you probably saw the version from a 0:33:31.840 --> 0:33:34.640 company called Hallusion art Prints. 0:33:34.600 --> 0:33:36.760 And art prints emphasis on art I think. 0:33:37.560 --> 0:33:41.840 Yeah. And so these guys, Paul Huber, who's an aerospace engineer, 0:33:41.880 --> 0:33:46.440 and a software engineer named Mike Belinsky, they were turned 0:33:46.440 --> 0:33:48.120 on by these things too, and they said, hey, this 0:33:48.240 --> 0:33:50.960 is pretty great. We're two smart guys. We can build 0:33:50.960 --> 0:33:54.800 our own computer program and algorithm to make these things ourselves. 0:33:54.880 --> 0:33:58.640 And they started making these posters in ninety two, and 0:33:59.000 --> 0:34:01.840 that those were the Hallusion art prints that you would 0:34:02.120 --> 0:34:03.680 most likely those are the ones. Like I said that 0:34:03.720 --> 0:34:06.080 you were seeing it at the kiosk for about twenty 0:34:06.120 --> 0:34:08.760 to twenty five bucks. These guys were printing these things 0:34:08.760 --> 0:34:13.879 for a quarter. Even with like if they're wholesaling these 0:34:13.880 --> 0:34:16.440 things to the kiosk, they're still making some pretty good 0:34:16.480 --> 0:34:17.920 dough off of that. Yeah, kind of mark. 0:34:17.840 --> 0:34:20.520 Maybe ten bucks something like that off. 0:34:20.400 --> 0:34:23.160 A poster awsome a quarter. It's good return. 0:34:23.280 --> 0:34:26.279 Heck, yeah it is. And they started churning these things out. 0:34:26.320 --> 0:34:28.520 But like I said, there's an emphasis on art prints, 0:34:28.560 --> 0:34:30.960 Like they kind of saw theirs as it was different. 0:34:31.000 --> 0:34:33.879 It was distinguished from the other ones because they were 0:34:33.920 --> 0:34:36.920 just so well made. The problem is is people are like, 0:34:37.239 --> 0:34:39.520 that's great, I can still get the same effect from 0:34:39.560 --> 0:34:41.919 a similar one from one of your competitors for five 0:34:42.000 --> 0:34:45.120 dollars at Spencer's rather than twenty five dollars at your 0:34:45.400 --> 0:34:48.920 admittedly very charming Kiosk. Right, I'm gonna go with the 0:34:48.960 --> 0:34:52.200 five dollars one. And so they set themselves up for 0:34:52.280 --> 0:34:54.239 some pretty serious competition out of the gate. 0:34:54.840 --> 0:34:57.520 Yeah, big time. And there are all kinds of people 0:34:57.560 --> 0:35:00.440 pumping these things out. But like you said, you go 0:35:00.520 --> 0:35:03.200 to the Kiosk, you get your ears pierced, sure by 0:35:03.200 --> 0:35:07.920 a top quality seventeen year old twenty five times. Excuse me, 0:35:08.360 --> 0:35:11.439 Oh don't know. I meant purchase a top quality poster. Okay, 0:35:11.480 --> 0:35:13.120 but yeah, you're also getting your ear piers by a 0:35:13.160 --> 0:35:18.080 top quality seventeen Claire's piercing Pagoda or Claies or something. 0:35:19.480 --> 0:35:22.680 So Basha their company started to fade a little bit 0:35:22.719 --> 0:35:26.400 because of the competition, and he thought, like when he 0:35:26.440 --> 0:35:31.239 was interviewed in ninety four by Ink magazine, he thought 0:35:31.280 --> 0:35:33.560 this was like, Hey, this is the beginning. We're going 0:35:33.640 --> 0:35:36.799 to be huge. His literal quote was talking about being 0:35:36.840 --> 0:35:40.440 a Disney of the twenty first century and like making 0:35:40.480 --> 0:35:43.879 it into a big multimedia company. And then many years later, 0:35:44.040 --> 0:35:48.200 in like the late twenty sixteen or twenty seventeen, he 0:35:49.080 --> 0:35:52.760 reflected back and said, well, as it turns out, maybe 0:35:52.760 --> 0:35:55.480 that was just my fifteen minutes and it wasn't that 0:35:55.560 --> 0:35:58.560 much fun and it was really exhausting. He ended up 0:35:58.600 --> 0:36:03.680 selling his majority State and Anything to Smith and another 0:36:03.719 --> 0:36:07.239 one of the employees there who renamed it Magic Eye 0:36:07.640 --> 0:36:10.879 and Smith's Cherry Smith still owns the company today. 0:36:10.960 --> 0:36:13.879 Yeah, that original graphic artist he first partnered with, which 0:36:13.880 --> 0:36:15.200 is pretty cool. I think that's great. 0:36:15.239 --> 0:36:16.960 Yeah, you know, I bet they still make some dough 0:36:16.960 --> 0:36:17.800 off of this. Yeah. 0:36:17.880 --> 0:36:21.840 Can you imagine if today we were you know, you'd 0:36:21.880 --> 0:36:26.000 tell your friend I'm going to Anything Enterprises this summer 0:36:26.360 --> 0:36:30.720 and then we say World or Land. Yeah, just doesn't 0:36:30.760 --> 0:36:34.200 quite have that ring, you know, No, it doesn't. So, Yeah, 0:36:34.239 --> 0:36:37.440 that fad ran its course. Even during the heat of it. 0:36:37.520 --> 0:36:40.520 Everybody but Boshet was well aware this is a fad, 0:36:41.000 --> 0:36:43.880 and he knew, but he was hoping beyond hope that 0:36:43.960 --> 0:36:47.520 he could turn it and parlay it into something else. Right. Yeah, 0:36:47.520 --> 0:36:50.000 But as much as the rest of the world kind 0:36:50.000 --> 0:36:53.640 of moved on from stereograms. They proved to be a 0:36:53.760 --> 0:37:02.600 really useful training technique for people whose eyes don't align 0:37:02.680 --> 0:37:08.600 properly because of poor muscular development, people with strabismus in particular. 0:37:09.280 --> 0:37:13.239 Yeah, it almost they'll do like these little exercises. I'll 0:37:13.239 --> 0:37:15.400 give you these exercises to do, and it's almost like 0:37:15.640 --> 0:37:18.960 a workout for your eyeball, right, to build that muscle 0:37:18.960 --> 0:37:19.279 back up. 0:37:19.360 --> 0:37:22.680 Yeah, exactly. Apparently there's a critical window when you're young, 0:37:23.360 --> 0:37:26.839 I think up to about three maybe four where your 0:37:26.880 --> 0:37:31.080 brain learns to put together the two different pictures that 0:37:31.120 --> 0:37:34.239 it's eye, your eyes are giving it into one cohesive hole, 0:37:34.600 --> 0:37:37.480 and that if your eyes aren't aligned properly, or there's 0:37:37.520 --> 0:37:40.239 another condition where one eye is way more dominant than 0:37:40.280 --> 0:37:43.759 the other, your brain just disregards the picture from the 0:37:43.840 --> 0:37:47.319 non dominant or non aligned eye and just relies on 0:37:47.440 --> 0:37:52.040 the dominant or you know, straight eye and you don't 0:37:52.080 --> 0:37:54.880 see in depth. You just have monocular vision. You're getting 0:37:54.920 --> 0:37:57.520 information from both eyes. They both work just fine, but 0:37:57.600 --> 0:38:00.680 your brain's just disregarding one and so you you're what's 0:38:00.680 --> 0:38:04.240 called stereo blind. And they can correct that through surgery. 0:38:04.280 --> 0:38:08.160 But after surgery, they start showing you magic eye posters 0:38:08.200 --> 0:38:09.120 to train yourself. 0:38:09.920 --> 0:38:13.759 Yeah, Ruby had something. It wasn't exactly this, but she 0:38:14.040 --> 0:38:17.279 has has always had like when she's really tired, one 0:38:17.320 --> 0:38:20.680 of her eyes can go wonky. Yeah it is. And 0:38:20.800 --> 0:38:22.279 when she was little she wore a patch for a 0:38:22.320 --> 0:38:25.520 little while and then you know, we've kept taking her 0:38:25.520 --> 0:38:27.160 to the to the eye doctor all these years and 0:38:27.200 --> 0:38:30.080 they finally were like, you know, it's fine, Like she's 0:38:30.120 --> 0:38:33.560 she's basically corrected it. It still happens sometimes when she's 0:38:33.560 --> 0:38:36.759 super tired, and I'll just say, I'll say, maybe, you know, 0:38:36.800 --> 0:38:40.120 snap your eyes together, and she go zoop and she can. 0:38:40.200 --> 0:38:42.680 She can do it on purpose, so she kind of 0:38:42.760 --> 0:38:46.040 learned how to control it. I guess that's pretty cute. Yeah, 0:38:46.040 --> 0:38:46.640 it's interesting. 0:38:46.920 --> 0:38:52.040 So if you wanted to make a magic eye puzzle, Uh, 0:38:52.080 --> 0:38:55.160 there's just a few things you need to know. Actually 0:38:55.160 --> 0:38:57.400 you do. You don't really need to know anything about 0:38:57.400 --> 0:39:02.000 it because today there's so many free like like stereogram 0:39:02.080 --> 0:39:04.279 building software available. 0:39:05.400 --> 0:39:06.840 You know, you need to know how to type the 0:39:06.840 --> 0:39:08.800 word sailboat pretty much. 0:39:09.200 --> 0:39:11.440 As a matter of fact, I was looking on how 0:39:11.480 --> 0:39:14.480 to make a stereogram. I found an Instructibles article and 0:39:14.520 --> 0:39:17.080 I opened it up said eight steps to making a 0:39:17.200 --> 0:39:22.560 stereogram or auto stereogram image. Step one was download a 0:39:22.600 --> 0:39:29.000 stereogram maker program. Key, yeah, exactly. But what you're doing is, 0:39:29.960 --> 0:39:31.400 i'd say, we just kind of talk about how they 0:39:31.400 --> 0:39:33.359 work real quick, okay before we eat. 0:39:33.440 --> 0:39:33.640 Yeah. 0:39:34.080 --> 0:39:36.080 I still don't quite get it. I mean I kind 0:39:36.120 --> 0:39:37.960 of know how you can see one, but I still 0:39:38.000 --> 0:39:39.239 don't quite get how they're made. 0:39:40.840 --> 0:39:45.400 Oh I don't either. Ohh so mean, okay, I don't. 0:39:45.440 --> 0:39:48.040 Actually there's a little bit that I kind of understand. 0:39:48.080 --> 0:39:53.160 But from what I gather, they you take your image 0:39:53.600 --> 0:39:56.799 and you make it separately. Right, So when you're when 0:39:56.840 --> 0:39:59.719 you're looking at a magic I poster, there's usually not 0:39:59.800 --> 0:40:02.399 much detail, especially in the ones from the nineties. It's 0:40:02.480 --> 0:40:05.560 a star, it's a ball, it's a I think it's 0:40:05.560 --> 0:40:09.640 a dragon kind of thing. It's just an outline a silhouette. 0:40:09.719 --> 0:40:13.400 And they've gotten way more sophisticated since then to I 0:40:13.520 --> 0:40:15.919 saw one today that was a squirrel and you could 0:40:15.920 --> 0:40:18.200 see the pupil in the squirrel's eye like it was 0:40:18.440 --> 0:40:19.760 really sophisticated. 0:40:19.960 --> 0:40:20.720 Oh wow, they've. 0:40:20.560 --> 0:40:23.240 Gotten really good at it. But what they do whether 0:40:23.280 --> 0:40:27.879 it's primitive or really sophisticated. They're taking that image making 0:40:27.960 --> 0:40:31.600 a silhouette, but they're giving the silhouette depth using gray scale. 0:40:32.000 --> 0:40:35.880 So the lighter the gray color shading there is to 0:40:35.960 --> 0:40:39.000 the silhouette, the closer it is to you, the darker 0:40:39.040 --> 0:40:41.160 it is, the further way it is. Just like you 0:40:41.160 --> 0:40:44.359 wouldn't like a regular like a charcoal drawing of something, right, 0:40:44.600 --> 0:40:47.600 except there's nothing in the middle. And then the computer 0:40:47.800 --> 0:40:52.080 program takes that computer generated image and it assigns different 0:40:52.160 --> 0:40:56.120 values depending on how light or dark along the gray 0:40:56.160 --> 0:40:59.800 scale each pixel is, and that's how much it gets displaced. 0:41:00.000 --> 0:41:03.280 The lighter it is, the further away it gets just placed, 0:41:03.400 --> 0:41:06.360 the more it's gonna pop out towards you, which indicates 0:41:06.400 --> 0:41:09.600 that this part of the pictures in the foreground, it's 0:41:09.680 --> 0:41:12.240 closer to you than say the rump of the squirrel. 0:41:12.880 --> 0:41:15.399 Yeah, so the white parts would be closer, the dark 0:41:15.440 --> 0:41:18.840 parts would appear more distant, and that creates the depth. 0:41:19.440 --> 0:41:22.120 But then you still have to have that repeating pattern 0:41:22.200 --> 0:41:24.960 laid out over the top of it, right, And I 0:41:24.960 --> 0:41:28.319 mean that's basically you put that repeating pattern on top 0:41:28.760 --> 0:41:32.600 and these vertical strips or rather a computer does, and 0:41:32.640 --> 0:41:35.640 then that that program just translates the shades of those 0:41:35.680 --> 0:41:41.200 pixels onto that depth map and via magic it all 0:41:41.200 --> 0:41:43.160 comes together. Yeah, magic in program. It's neat. 0:41:43.160 --> 0:41:45.279 And when I say sophisticated, I mean it. I saw 0:41:45.320 --> 0:41:47.440 it in today. I'm really sad I didn't send it 0:41:47.480 --> 0:41:50.319 to you. I meant to. But it is basically a 0:41:50.360 --> 0:41:53.360 coral reef scene with different you can tell the different 0:41:53.400 --> 0:41:56.799 kinds of fish, Like there's different clownfish closer in the foreground, 0:41:57.600 --> 0:42:00.440 there's like triggerfish in the background, Like there's a middle 0:42:00.480 --> 0:42:03.280 ground to the whole thing. Like that's how good they've gotten. 0:42:03.560 --> 0:42:05.839 And like I was saying initially, when you see it 0:42:06.480 --> 0:42:09.080 and you really see it, you can start looking around 0:42:09.160 --> 0:42:13.319 inside the image. It's they it's just so amazing. You 0:42:13.320 --> 0:42:16.880 just look up, like I guess, I think I searched 0:42:16.920 --> 0:42:21.920 sophisticated stereograms or magic eye or something like that, and 0:42:21.960 --> 0:42:23.640 it brought up some really good ones. 0:42:24.360 --> 0:42:27.239 Yeah, it's uh. And what you mentioned earlier about like 0:42:28.200 --> 0:42:29.959 the fact that you couldn't see him for so long, 0:42:30.480 --> 0:42:33.719 you can only have this feeling once, which is not 0:42:34.000 --> 0:42:36.399 ever being able to see one, to finally seeing your 0:42:36.400 --> 0:42:41.200 first one. And when that picture jumps out from the 0:42:41.239 --> 0:42:45.600 poster the very first time. It is like it's a thrill. 0:42:45.760 --> 0:42:48.399 You're like, I finally got it. I see what you mean. 0:42:48.480 --> 0:42:51.920 Because there's also this idea, which of course isn't true. 0:42:51.960 --> 0:42:54.720 But you know, I remember when they first came around 0:42:54.840 --> 0:42:57.120 that I thought it was like some people thought it 0:42:57.160 --> 0:43:01.080 was like a snipe punt, right, Yeah, there is no picture, 0:43:01.120 --> 0:43:02.560 and it's just a way you fool your friends and 0:43:02.719 --> 0:43:05.080 staring at a thing for an hour. So when you 0:43:05.120 --> 0:43:07.239 finally have it jump out and it's proven to you, 0:43:07.560 --> 0:43:09.440 it's a pretty remarkable feeling. 0:43:09.560 --> 0:43:11.919 It is, And there were a couple over the last 0:43:12.080 --> 0:43:13.680 day or so where I was like, wait a minute, 0:43:13.760 --> 0:43:17.880 is this Surely somebody out there has done that for fun. 0:43:17.960 --> 0:43:20.520 But yeah, the whole thing wasn't just a big in joke. 0:43:20.560 --> 0:43:22.479 I'm sure some people thought that for real. 0:43:23.200 --> 0:43:25.279 Yeah. So the trick that you can use, there's a 0:43:25.320 --> 0:43:28.040 few tricks. One is the one I mentioned earlier, is like, 0:43:28.920 --> 0:43:31.480 if it's not a poster and it's a piece of paper, 0:43:31.600 --> 0:43:34.080 you can hold hold it very close to your nose 0:43:34.800 --> 0:43:36.919 where you can't even really focus on it, and very 0:43:37.600 --> 0:43:41.279 slowly pull it away, but try and keep your try 0:43:41.320 --> 0:43:45.160 not to focus on it still. Some many of them 0:43:45.160 --> 0:43:48.719 will have two little objects, like two dots above the 0:43:48.760 --> 0:43:51.600 whole thing, and they say, like, stare at those and 0:43:51.680 --> 0:43:53.319 unFocus until you see three of them. 0:43:53.520 --> 0:43:54.359 Wasn't able to do that. 0:43:55.160 --> 0:43:57.320 I am not able to do that either, or maybe 0:43:57.480 --> 0:43:59.960 I didn't try long enough. But I always just base 0:44:00.480 --> 0:44:03.040 once I did the nose trick, and you have sort 0:44:03.080 --> 0:44:04.680 of taught your eye, like I said, you can just 0:44:04.719 --> 0:44:07.480 sort of get it by just sort of unfocusing in 0:44:07.520 --> 0:44:09.120 the middle distance. 0:44:08.880 --> 0:44:11.279 Right, Yeah, that's the way that I do it. Just 0:44:11.320 --> 0:44:13.719 relax the eyes and let it. Yeah, you just gotta 0:44:13.760 --> 0:44:14.280 be patient. 0:44:14.920 --> 0:44:15.680 Gotta be patient. 0:44:16.880 --> 0:44:19.520 I guess that's it. I think basically everybody should go 0:44:19.560 --> 0:44:23.280 out and start looking at auto stereograms. Huh. 0:44:23.360 --> 0:44:26.320 Yeah, they're not a joke. Nope, they're really neat images 0:44:26.360 --> 0:44:26.960 are really there? 0:44:27.040 --> 0:44:30.479 Yeah, the first time, like you were saying, you see 0:44:30.480 --> 0:44:34.080 one pyrotechnics go off and the final countdown starts playing, 0:44:34.120 --> 0:44:35.880 it's it's triumphant. 0:44:36.040 --> 0:44:38.160 It's pretty well you always had the final catin I'm playing, 0:44:38.200 --> 0:44:39.160 So that's probably what that was. 0:44:39.320 --> 0:44:41.839 Yes, I do you got anything else? 0:44:42.640 --> 0:44:43.399 I got nothing else? 0:44:43.440 --> 0:44:43.719 All right? 0:44:43.760 --> 0:44:44.200 Everybody? 0:44:44.200 --> 0:44:46.160 That means, of course, it's time for listener mail. 0:44:48.680 --> 0:44:52.000 So, my friend, I'm just gonna pick one at random. 0:44:52.040 --> 0:44:55.680 And when I say randomly select, I mean randomly select 0:44:55.719 --> 0:44:58.760 from the large pool of people who wrote in about 0:44:58.760 --> 0:44:59.239 your mask. 0:45:01.280 --> 0:45:04.600 Oh, we talk about this. I guess I did not 0:45:04.640 --> 0:45:05.200 see this one. 0:45:06.000 --> 0:45:09.000 If you remember from the short stuff episode recently on 0:45:09.080 --> 0:45:12.800 Fahrenheit to Celsius conversion, I even commended you on the 0:45:12.800 --> 0:45:15.239 show for being brave enough to try public math again 0:45:16.520 --> 0:45:19.160 and apparently didn't get it right again. 0:45:20.280 --> 0:45:22.040 Is it really a surprise to anybody though? 0:45:23.760 --> 0:45:25.480 I don't know, is it? 0:45:25.640 --> 0:45:25.680 No? 0:45:27.560 --> 0:45:32.080 Let me see here. Let's go with Jake Eichenberger. Hey, guys, 0:45:32.200 --> 0:45:34.080 I haven't laughed out loud to myself in a while, 0:45:34.120 --> 0:45:37.239 but hearing Chuck compliments Josh Bravery with attempting live math 0:45:37.480 --> 0:45:39.719 really hit the spot. I'm sure you get a lot 0:45:39.760 --> 0:45:43.560 of emails. But for Celsius to Fahrenheit, you add the 0:45:43.560 --> 0:45:48.400 thirty two after the multiplication, not before. And I always 0:45:48.400 --> 0:45:52.600 treat one point eight as diprection nine fifths because five 0:45:52.719 --> 0:45:55.719 is easy to deal with. So, for instance, for twenty one, 0:45:56.200 --> 0:45:58.680 I would use twenty plus one because I use the 0:45:58.680 --> 0:46:00.840 fact that twenty is easily to divide by five to 0:46:00.920 --> 0:46:05.920 my advantage here. So jeez, now I don't understand any 0:46:06.000 --> 0:46:10.319 of this, so blah blah blah math stuff. Now add 0:46:10.360 --> 0:46:13.360 the thirty two they came up with thirty six, So 0:46:13.400 --> 0:46:16.319 thirty six plus thirty two is sixty eight. And don't 0:46:16.320 --> 0:46:19.200 forget about the plus one from earlier. Every one degree 0:46:19.239 --> 0:46:21.759 celsius is one point eight, so sixty eight plus one 0:46:21.760 --> 0:46:24.759 point eight would be sixty nine point eight as the 0:46:24.800 --> 0:46:26.160 optimal butterfly temperature. 0:46:26.280 --> 0:46:29.120 Yeah, I like my version better, even though it produces 0:46:29.120 --> 0:46:30.279 incorrect results. 0:46:32.480 --> 0:46:34.160 I mean I wouldn't even have tried it, So hats 0:46:34.160 --> 0:46:34.799 off to you for that. 0:46:34.840 --> 0:46:37.040 Thank you, thank you for still commending me, and thank 0:46:37.080 --> 0:46:39.040 you to uh who. 0:46:38.680 --> 0:46:42.120 That was just Jake, and let's say all the others. 0:46:41.960 --> 0:46:46.040 Jake at all, I appreciate you guys for correcting me. 0:46:46.920 --> 0:46:51.160 Thank you for that.
