Optical Illusions

Packed from cover to cover with a huge range of brand new optical illusions, you'll find a dizzying variety of visual conundrums on every page of this book. It's a place where objects vanish right in front of your eyes, straight lines start to bend and stationary items get up and slide around the page.

​

To make sense of these strange phenomena a handy visual interpreter is included with a key so you know which section to use on each puzzle. It will reveal colours that change and shapes that alter in size, helping you make sense of what your brain can't process.
