Scientific American Library's Illusions — Simon & Schuster

The third disc in the Scientific American series, ILLUSION: THE DOORS OF THE MIND is the ultimate head trip--a cd-rom filled with illusion games that let users discover first-hand how human beings visually perceive the world around them. Based on two noted Scientific American Library books, Perception by Irvin Rock and Eye, Brain and Vision by Nobel Laureate David H. Hubel, the disc features interactive "impossible figure" puzzle games that explore depth and color perception, and a panoply of other games that investigate motion detection and shape memory; a series of multimedia galleries featuring people with unique perceptual experiences such as a cinematographer and a race car driver; and a direct link to a specially-created World Wide Web Site.
