This intriguing collection contains more than 275 optical illusions that appear to change before your eyes. Al Seckel carefully selected both well-known images, such as Shepard's tabletop, Wade's spiral, Ames room and Rubin's face/vase, and many lesser-known, but no less effective, illusions. Every type of optical illusion is here, along with notes about the science of each visual perception and how the illusions work. Among the baffling images and shapes are: Figure/ground illusions, in which one shape switches into another then back again; Ambiguous figures; Impossible objects; Trompe l'oeil; Stereo illusions. With illusions rendered in photography, artwork and computer imaging, and a huge variety of themes and effects, Optical Illusions dazzles both the mind and the eye.
