"Jacques Ninio, an international authority on visual perception, here explores the fascinating world of illusions. His book features a stunning array of illustrations, including many images seldom seen in books on the topic. The art ranges from classical illusions inspired by rainbows, mirages, and other oddities of nature; to figures from seventeenth-century physics texts that Ninio himself unearthed; to spectacular new illustrations in which motion is perceived in fixed images."--BOOK JACKET.
