Aki Nurosi and Mark Shulman, the authors of Colorful Illusions, are here to play more astonishing visual tricks. These brain-bending, mind-blowing, all-in-color optical illusions will really fool your eyes. Each is a colorful masterpiece, created to appeal to wide-eyed children, design students, and art lovers. Hold on to your hats--two fancy stovepipe hats: can you tell whether they're taller than they are wide, or wider than they are tall?" Try climbing the wild set of stairs; they'll have you going in circles and in squares. Other cool illusions include the Sander Parallelogram, the Necker's Cube, and the "Defective Perspective" with its false 3-D.
