Gödel, Escher, Bach

I finished a book today that I've been chewing on all summer. It's called Gödel, Escher, Bach: An Eternal Golden Braid, and I highly recommend it to everyone who is interested in computer science, the nature of consciousness, music, art, postmodernism, artificial intelligence, Lewis Carroll, Zen Buddhism, logical systems, genetics, wordplay, etc. I'm not sure how to describe this book except as a short course in the interconnectedness of everything and how much fun intellectual exercise can be.
