"The brain is an amazing thing, but it doesn't always get things right when it comes to sight. This book is here to explain why, with astounding images, baffling puzzles, and simple reveals which show the reader how each trick works. Templates included at the back of the book reveal answers and aid the creation of astounding illusions. The science behind each element will be simply explained in an engaging way, to encourage the reader to find out more each time. Throughout the book will be chances for the reader to get hands-on with the illusions, with step-by-step experiments, or tips on how to draw your own "moving" optic art on paper or on the computer"--Publisher's website
