#ScribesAndMakers day 27: What's a book that made you see the world differently? How?
William Poundstone's _The Recursive Universe_ taught me far more about recursion, complexity and how it can arise from simplicity, information and how it differs from data, entropy, and the universe itself, than I can possibly do justice to in 500 characters — or even a multi-post thread. It's up there with things like Sagan's _Cosmos_ and Hofstadter's _Gödel, Escher Bach_ and _Metamagical Themas_.
