I'm open-minded and always looking to learn new things or meet new, interesting people. This is a bit at odds with my more introverted and slightly nerdy side, but I think in the long run it balances out nicely. :)

Right now I'm trying to juggle my job (which I love), my obsession with making music, my curiosity for foreign countries, cultures, cuisine and languages, and the occasional workout/bike ride.

... problem solving, which comes in handy in my line of work.
... listening to people.
... talking about music for hours. :)

I guess it must be my hair, which is unusually grey for my age. It's genetic, and it doesn't bother me enough to start dyeing it.

I've tried to come up with the ultimate favorites, but it's just impossible. So what you can see below is a snapshot of what came to my mind the last time I updated this.

Music: nowadays I'm mostly into the darker shades of electronic music (drum & bass, dubstep, etc.), but I'm open to many different genres. In general I tend to prefer music that is either a bit dark, a bit crazy or both. :) A few more popular favorites: Massive Attack, Lana Del Rey, Nine Inch Nails, Alicia Keys, The Dillinger Escape Plan, Imogen Heap, Björk, Audioslave, Garbage, Radiohead, ... I could go on, but you get the idea.

Books: The Hitchhiker's Guide to the Galaxy, The Lord Of The Rings, cyberpunk novels like Snow Crash and Neuromancer

Movies: 21 Grams, Aliens, Pulp Fiction, Mulholland Drive, Trainspotting, Fight Club, ...

TV Shows: Six Feet Under, Dexter, Californication, Weeds, Skins, How I Met Your Mother, Friends.

Food: Thai, Indian, Chinese, Japanese, Middle Eastern, etc. Not a fan of typical greasy Hungarian stuff though.

Music, friends, a computer, the Internet, contact lenses and interesting projects.

I do tend to think about hard problems I have to solve at work, especially while I'm commuting.
On a less nerdy note, I also think about my current and future music projects, I tend to replay conversations in my head, and sometimes I obsess about ridiculously insignificant things, before I catch myself and stop. :)

... with friends, at a pub/concert/party, at home working on my music or wasting time on the Internet. :)

... you are open-minded, intelligent and have a good sense of humor. A healthy obsession with music and/or traveling doesn't hurt either, but it's not a must. :)
