Featured in four galleries, the book includes the well-known -- Shepard's Tabletop, Wade's Spiral and Escher's Impossible Box -- and the more obscure. Also included are notes about the stories behind the illusions and their inventors.

With illusions rendered in photography, artwork and computer imaging, The Great Book of Optical Illusions proves that these magical eye tricks never grow old. From a 12th-century Japanese Noh mask and optical tricks based on mathematical formulas, to illusions you can recreate yourself, all the world's most fascinating and startling optical illusions are here in one full color book.
