Query: Excellent book for the Mensa crowd

If you enjoy cuddling up with sentences such as:"Element information items are fairly adaptable to representing arbitrary data structures, as one simply needs to build an isomorphism between the "native" data structure and a tree-oriented graph of elements and character data"... then you'll enjoy this book immensely. Me - I'm too stupid and life's too short.
