Optical Illusions

Optical Illusions They say that seeing is believing, but what if the picture you see is hard to believe? Optical Illusions is a fascinating collection of visual puzzles and enigmatic designs that will have you wondering if not how they work then certainly what they contain. From baffling collections of shapes, which defy you to work out the hidden figures within them, to dazzling graphic patterns which will have you shaking your head when you focus on them to the cleverest of drawings whose skill will make you smile in disbelief as you count again and again the deceptive numbers of faces, arms, or legs which make the ordinary look extraordinary. Optical illusions have been delighting people for centuries and some have become familiar images on posters around the world. But artists, designers and scientists have continued to allow their imaginations to run wild and this has resulted in a compelling number of additions to the genre. In this lavishly produced collection of 150 color and black and white examples from Illusion Works, the world's leading brand of illusion artworks, you have the chance to see the results of their skills as well as enjoy some classic works. Prepare to be amused and intrigued as you experience a visual rollercoaster that will make you question your mind as well as your sight!
