Enter the world of visual magic where a random pattern of squares suddenly becomes a face, or when special glasses (found in the book) transform a dotted pattern into 3-D splendor. Thirty tricks and illusions will delight you for hours. Watch as a goldfish seems to vanish from a picture, try to figure out which of two goats is actually bigger, and focus on the workings of some “impossible” shapes.

From School Library Journal

Grade 5-9-- A presentation of more than 30 intriguing optical illusions accompanied by clear, brief explanations. With many full-page illustrations, plenty of white space, and excellent reproductions, the book is accessible and inviting. The illusions are well chosen to demonstrate various aspects of ``visual magic,'' including lines, color, brightness, and depth. Instructions on how to view the illusions are sometimes followed by brief explanations of how the effect is caused. Unfortunately, two punch-out props--three-dimensional glasses and a spinning disk--are essential for several of the examples to be effective. If libraries can get past this difficulty, this is an attractive browsing book that will complement more informative (but less graphically appealing) books such as Lawrence White's Optical Illusions (Watts, 1986) and The Optical Illusion Book (Morrow, 1984) by Seymour Simon. --Steven Engelfried, Pleasanton Library, CA
