Fletcher, A. (2001). The art of looking sideways. London ; New York: Phaidon.
Fun and inspirational. When I'm searching for ideas or have a great need to be distracted with interesting, fun, creative ideas, I turn to this book - always conveniently stored by my living room couch - and open up to a random page and read a few pages. Works every time. And it has over 500 pages, so this covers innumerable sessions. Brilliant, creative, fun. Is it an important contribution to knowledge? No, not really. Is it essential reading? No, not really. Is it something to read from start to finish? Nope. Will you enjoy it and get inspired? Yup. That's why I recommend it.
