free software/culture; it's more of a way of life than anything. I'm far from being a guru, advocate/activist, developer or anything like that, but still... I use it, occasionally write a review or something, send a Czech translation to upstream, file a bug report... and I'm quite active at few local forums.
DIY stuff; after building my ergodox and modding few keyboards, I'd like to recable all my headphones, build an amp, make a frankentrackball and few other rather simple things if nothing else.
computer science, math linguistics etc.; I study CompSci and will possibly get into linguistics soon, I've always sort of wanted to do that, but I'd love to do some keyboard layout analysis first (oh, keyboards again).
gaming; I used to play a lot of NHL, RTS and rogue-like games many years ago, then left it because I didn't like the direction game industry was heading. Now I play indie, free or old games every now and then, usually only to enjoy the storyline... I mean, I've just played SC:BW at like 40 apm, that probably gives you some idea. I've always wanted to make my own game, I remember how I enjoyed D&D-like games and creating own mods for strategic games, maybe I'll find more time to get into game design soon. BTW I'm one of those people who watch SC2, but never play it (I mention it because of our Captain).
Apart from the stuff above, I've been a metal fan for years, now I'm starting to explore classical music and electronica, it's fun. Unfortunately, I had to give up playing the guitar&recorder due to a hand injury. I've quit martial arts, most sports including competitive running (I was in the 20 in the town even without any training program), anime, reading (especially science mags and SF), foreign languages and plenty of other things.
