Richard Wiseman’s recent blog post on the best optical illusion i’ve seen all year”  reminded me of one of my favourite books and is must for all you creative types and graphic designers.Written by Alan Fletcher,The Art of Looking Sideways and is described as “an absolutely extraordinary and inexhaustible “guide to visual awareness,” a virtually indescribable concoction of anecdotes, quotes, images, and bizarre facts that offers a wonderfully twisted vision of the chaos of modern life”.It was in this book that i came across several optical illusions like the one Wiseman spoke of.Did some digging and found two others that are equally perplexing:
