Reading, designing and making my own clothing, learning (yes, I'm a dork), religions (I am fascinated by them and their workings even though I am agnostic), listening to music nearly constantly (I love it yet I can't play an instrument, I'm lacking that talent thing), philosophy, debating, a chronic addiction to webcomics, and probably other things that I haven't listed.
People I can have meaningful conversations with that are deeper then a puddle. I'm generally not picky about who I talk with though.
I try and be open and give everything a chance, be it darkwave, EBM, synth, industrial, trance, D&B, jazz, punk, opera, ska, prog-rock, or anything else. Music is there, not to make you look better, or fit in, but as something to be loved for the artistry behind it, no matter where or when it may have come from. You may dislike a certain genre, but you may still find some music within it that you will absolutely love.
Ghost In The Shell (both of them), Serenity, Appleseed (remake), The Dark Crystal, The Abyss, Phantom Of The Opera, Monte Python & The Holy Grail, and a few others that I can't think of at the moment
I don't really watch much television, but I will watch Invader Zim, The Daily Show, Mythbusters, and just about anything on the Science Channel.
My favorite authors include Michael Crichton, Douglas Adams, Orson Scott Card, and Stephen Baxter.
I don't quite have so much heroes then I have people I admire for what they have done. Jacques Cousteau (I wanted to be a marine biologist for the longest time, until I found out that I would probably only get a job either for the government or a fishery), Albert Einstein, Mohandas Gandhi, Max Planck, Werner Heisenberg, Neil DeGrasse Tyson, Stephen Hawkings, P.Z. Myers and quite a few others.
