Seeing shouldn't always be believing... It all depends on how you look at it--every one of these drawings has a built-in "deception." For example, in this picture how many cubes are there: 7 or 8? Count again: if you're focusing on the black tops, you'll come up with 8, but if your eye is on the white bottoms, you'll find 7 cubes. Some images show two things in one, others confound your perception so you won't be able to judge size, and still more seem to sparkle and pulse. You won't be able to take your eyes off them! 96 pages, 86 b/w illus., 4 x 5.

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 checkerboard closely; it will seem to pulsate and shimmer. And do those black-and-white patches actually link up to form the petals of a flower? Determine which twin brother has a bigger appetite by glancing at a drawing of both. (These guys don't look the same...or do they?) The only thing that won't be an illusion is the fun you're having.

DO NOT believe everything you see, because these amazing, astounding, seemingly impossible illusions can "fool" your eyes. Open up this collection to view a wondrous array of optical effects: specks seem to move, grey spots appear and disappear, circles gyrate, patterns pulsate, and straight lines wave and bend. Shapes and drawings keep you from distinguishing what's there, and make you perceive things that aren't. Objects appear different from a distance than they do close up. They'll forever change the way you look at things.

Classic Optical Illusions

Brandreth, Gyles Daubeney

The puzzles in this book are optical illusions. They are straight lines and perfect circles and two-way tricks and other shapes and drawings that keep you from seeing what's there-or make you see something that isn't there at all.
