Right now i'm stuck in Gödel, Escher, Bach: an "Eternal Golden Braid".
It's a book about music and artifical intelligence. The tagline "a metaphorical
fugue on minds and machines in the spirit of Lewis Carroll"

It's a look at the brilliant minds of mathematician Kurt Godel, graphic artist M. C. Escher,
and composer Johann Sebastian Bach, computer-science and cognitive-science professor
Douglas Hofstadter ties together the aesthetic gift of pattern recognition and manipulation
with theories on artificial intelligence, human intelligence, and the essence of self-awareness.

I keep having to start over because it's difficult. I put it down and it lays in wait until I decide
to take it up again. Starting over is just as interesting as it was the first time I read it.
