No... Its not just animation. The alternating images tricks ur brain. BUT this gives me major headaches almost immediately.

While yes animation does sort-of give the perception of 3d, the images here really do appear to have depth in the monitor. Its a cool trick. Now I am guessing we need to play this at a rate of 30fps each image (thus 60fps) or so so that we don't "see" the non-3d image alternations but we experience it nevertheless without a headache I might add.
