365 Optical Illusions

Why not experience a mindbender every day? This book is a great way to enjoy an optical illusion every day or take them in all at once. 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. There are illustrations, paintings and graphics, as well as color and black and white photographs of scenes ranging from buildings to landscapes. 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.
An incredible 365 optical illusions.
