Anyone of you ever seen these full-color 3-d images that look like two slightly different normal photos (or I suppose some crazy person might have made one with a computer for the same effect) if looked at normally. Then if you cross your eyes so that the two pictures overlap, it looks 3-d.

I bumped into them on a finnish site, (http://www.riemurasia.net/jylppy/media.php?id=35476), but haven't been able to find them anywhere else, even by googling. This may be because the words in the term for them (the one I know anyways) have several other uses and the ones to do less with actual images come up first in google

So... anyone know where to find more?
