This is a pretty broad category isn't it? I'm interested in things that are interesting. Yeah, I've also got a tattoo fetish as well as my piercings. I'm a website designer who hates HTML. Now that's interesting.
(Death) Metal, Punk, Classic Rock, Industrial, and any Techno with a hard driving beat.
The Hitchhikers Guide series. The Stand. Memoirs Found in a Bathtub. Stranger In A Strange Land. This list could be very long but I'll stop there.
