There is something intrinsically satisfying about optical illusions – static pictures that appear to move, change color, or fool us into seeing things that “aren’t really there.”

Optical Illusions, a new book by Paul M. Baars, covers illusions of depth, inversions, vibration effects, ambiguous figures, camouflage, anamorphic art, tessellations, and other visual brain teasers. (Yahoo News)
