I find pretty much everything interesting. Lately I've been getting into electrical engineering and physics. Even more lately, architecture has been my main interest... I figure I spend most of my time in buildings, ought to know something about how they're designed.
A whole long list of dead people... oh, and michael moore so I can spit in his face.
Lately: Nightwish, DragonForce, Sonata Arctica, Cromdale, Kovenant, Dropkick Murphys, Midnight Oil, Bad Religion, Leningrad Cowboys.Generally: I tend to listen to just about everything except top-40 and modern rap, although there are occasional decent songs even in those categories.
Gangs of New York, Serenity, Dr. Strangelove, Gattaca, Three Kings, The Boondock Saints.
Don't own one, but I watch Simpsons and South Park through downloads. And other shows (i.e. Firefly) from DVDs.
The Art of War, Les Miserables, The Fountainhead, Ender's Game, Armor, Cryptonomicon.
