Has anyone ever encountered stereograms (i.e. "magic eye" pictures) that encode separate images in the vertical and horizontal axes -- that is, if you hold the picture one way and look "into" it you see one thing, but if you rotate it 90 degrees and look into it you see something else? I've never seen or heard of such a thing, but it just occured to me that A) they should theoretically be possible to make, and B) if they are, that would open up some interesting effect possibilities -- pseudo-hypnosis, perceptual manipulation, dual reality, etc. Random, goofy example: You show a stereogram, people look into it and see that it's a dinosaur. Someone secretly chooses a card, concentrates on it, and imagines burning the image of it into the picture. Someone else then looks into the picture, and announces that the dinosaur now has an Eight of Clubs next to it. Dear god, that was the card the first spec was thinking of! Afterward everyone can look into the picture as much as they like, and see only the dino, no card.
Every problem contains the seeds of its own solution. Unfortunately every problem also contains the seeds of an infinite number of non-solutions, so that first part really isn't super helpful.

It's not possible to make using the same dots for any two images, but your post gave me another idea. I've been using this to make two images visible at the same time, one concave half sphere and one convex half sphere and the result was a transparent ball. I could probably use the same technique to make a dual-axis stereogram since the dots from one stereogram would only look like noise while viewing the other.
One thing I made for my old Amiga500 was animated stereograms, like bouncing balls or butterflies with flapping wings. I always thought that we in the future would be able to see whole animated movies like that, but apparently what I did didn't catch on. /Tomas |
