Optical illusions trick your mind and confound your perception, and that's why these images--including three-dimensional mazes--will drive you crazy in the best of ways. Stare at a circular... This description may be from another edition of this product.
I've seen some of the illusions in this book in the ripleys believe it or not museum. Some of the illusions involve turning a picture upside down and seeing a totally different picture, mazes, those black and white optical illusion spirals that looks like their moving, thinking puzzles and much much more. Worth every cent.
