Mines Albert Einstein, not only was he brilliant and probably one of the best abstract thinkers of all time, but he held himself well. Never went insane like most other genius's, and came out with a good quote or two. Also his views on God and religion fall pretty much in line with mine.
I've also been really getting into Stanley Kubrick recently. The imagery in 2001:Space Odyssey is stupidly beautiful.
First one to mention the guy who fronts Neutral Milk Hotel loses all my respect.
