You won't believe your eyes, and perhaps you shouldn't. Once you read this book, you'll understand how your perception can be skewed by the way your brain processes certain input. Using information learned from previous experiences, your brain tries quickly to make order out of what you're seeing. Page after page of illusions will have you reaching for a ruler to see if lines really are the same length or if the sides of that square are straight or bowed. Author DiSpezio presents many classics, such as the ambiguous drawing that might be a vase and might be two faces, as well as some less familiar ones. There are even directions on how to make some of your own magic. A few pages are a little confusing where a busy background interferes with an illusion or the layout makes the text difficult to follow, but it is worth the extra effort to read carefully, because you won't want to miss any of these visual tricks.
Illustrated in full colour, these optical illusions are cool and fun for all ages. Entertain yourself or impress your friends for hours.
Boggle your mind with afterimages, impossible figures, flip-flopping faces, and more that will confuse your vision. Figure out what the secret message is in letters that are stretched out. Look at two lines and decide which one is longer (or are they both the same length?). “Bend” a rigid pencil. Stare at a pattern of triangles and see how your mind organizes them into all sorts of imaginary patterns, shapes, peaks, and shades.
There’s only one thing you can be sure of when it comes to optical illusions: Appearances are deceiving!
