Pi

Just watched the movie 'Pi' on Channel 4, I'd heard it was a good movie. I got into it to begin with, but then it got a bit boring and I ended up here. Got back into it when they played a bit of Orbital, the soundtrack was excellent (I read somewhere that 'Watching Windows' was in the film, but I didn't hear it).
What did I learn from the film? If life gets too much, use an electric drill on your head. Nice.
