  • 365 Optical Illusions

    AGES 8+

    Every page features an optical illusion from one of the three main types -- literal, physiological and cognitive. Literal optical illusions create images that are unique from the objects that make them. Physiological illusions occur when the eyes and brain are subjected to excessive stimulation by brightness, color, size, position, tilt or movement. Cognitive illusions are the result of unconscious inferences. All trick the mind into perceiving something altogether different than what the eyes see. The 365 illusions here are based on those variations. There are instantly recognizable classics that trick the eye no matter how many times you see them, and dozens of new ones, like astounding sidewalk illusions and masterful architecture. Concise text includes a hint about the illusion -- for those who can't ''see'' it -- and a short description of how it works. Bright, colorful and sure to boggle, this is an ideal gift selection for all ages.
