3D pictures are interesting, but they rely on glasses that alter the way your left and right eye perceive images. This cool 3D image-creation technique doesn't require glasses but still produces a 3D illusion.

Instead of taking two images and combining them into one with each image highlighted in red and blue — or cyan and magenta, or any other colour used for anaglyph images — the two images are animated and "wiggle" back and forth, which creates the illusion of depth.
