Computer Programming, Pc Gaming, Linux, Music, Math, Puzzles, etc.
A wide variety really... Electronica, Industrial, Rock, Metal, some Punk Rock, etc. Deftones, Deviant, Tool, Nine Inch Nails, Assemblage 23, Front Line Assembly, Smashing Pumpkins, Depeche Mode, Apoptygma Berzerk, Social Distortion, The Cure, GooGoo Dolls, Toad the Wet Sprocket, Carbon 12 are the last few I played... =).
Horror/Suspense, Sci-fi, and a some Action and comedy. The Matrix, the Crow, Memento, Gattaca, Equilibrium, Se7en, PI, Fight Club, Lord of the Rings trilogy, and the Prophesy series are some of my favorites.
I watch very little TV. I like Discovery and TLC. Wish I had Comedy Central too. Masters of Horror, X-files, and Macgyver are among my favorite TV series.
hmmm.. computer books? As for Fiction, I read mostly Scifi and horror... Last few books I have been reading were Snow Crash, 12 Monkeys, Davinci Code, Do Androids Dream of Electric Sheep [Blade Runner], Count Zero, Wyrm, and Virtual Light.
