Meta: wiggle stereogram

Wiggle stereogram is an example of a stereogram in which left and right images are animated. This technique is also called wiggle 3D or wobble 3d.

These wiggle images usually contain two images. More intermediate images may also be used for smoother effect.

Wiggle stereograms have the advantage of not requiring any kind of glasses or special hardware, and it is easy to perceive the effect even for people with limited or no vision in one eye. Disadvantages of this technique are that it doesn't provide true depth perception, cannot be printed and it's harder to examine details on the image as it is constantly shifting.
