Optical Illusions--each a masterpiece of colorful design. Aki Nurosi and Mark Shulman, the authors of Colorful Illusions , are back to play more astonishing visual tricks. These exquisitely designed brain-bending, mind-blowing, all-color optical illusions will really fool your eyes. Each is a masterpiece, created to appeal to wide-eyed children, design students, and art lovers. Hold onto your hats-two fancy stovepipe hats, that is: can you tell whether they're taller than they are wide, wider than they are tall, or the same size? Or 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 simulated 3-D.
