When Lord? When the hell do I get to see the goddamn sailboat?

Here's how I do it: you'll notice that there's a repeating pattern, cross your eyes until you get two of the repititions to be on top of each other. Once you've done this you should find that the shapes pop out.

This is how I do it. The problem is that this inverts the depth map, because your right eye sees the left eye image and vice-versa.

To properly view them, you need to go wall-eyed, by focusing on something behind the screen. This is something that I have not been able to do yet.

Relax your eyes! I've never been able to see one of these things on a screen until now. Now that I have, I really want too see an animated one. The coolest thing so far is that you can click "redraw" and you'll cut to the next one and your eyes will already be focused for it.

Look, it's a schooner! ;) There's pretty recent music video that's all autostereogram: https://www.youtube.com/watch?v=2AKtp3XHn38 The dots at the beginning are helpful. I don't think MagicEye.js is fast enough to do a bunch of frames on the fly for some real-time animation, unfort. But if you already have the frames rendered you could stitch them together into a gif.

I did an animated 3d plasma for js1k some time ago. It's not fast but it's animated: http://js1k.com/2013-spring/demo/1412

h key toggles the height map.

It uses a simplified version of the MagicEye.js algorithm which generates horizontally repeating patterns for hard height changes in the source image. That's why I went with a plasma in the end.

If you don't quite have the knack for relaxing your eyes to see these, here's "one weird trick". Position yourself with something behind you (such as a window) that you can see reflected on the screen. Focus on the reflection so you are looking "through" the screen. Now re-focus on the screen, but not immediately! Hold your focus and let it "slip" as slowly as possible. At some point your eyes will converge at the ri…

Nope. Doesn't work. Everyone's advice fails to work for me. I tend to think this is just a mass conspiracy or giant elaborate joke. I'm going to use this JS script to generate tests to see if I can get people who can do this to tell what the number is behind this "magic eye". Call everyone on their bullshit.

never in my life i managed to see this things. even back then when they were in fashion. no matter how hard i tried. I'm starting to get worried something is wrong with me.
