I used to be fond of computers and comics.
Music obviously, a wide variety of music. I learn as much about it as I can. I have a big wall of vinyl records, compact discs and a smaller set of cassettes. I usually have to play them on old equipment, because I have some audio gear that almost never gets thrown away.
Anthropomorphic animal costumes (the dragon mask, arms, tail and feet I picked up recently) -- and novels, like Redwall.
Gargoyles (the 1990's television series, recently 2000's comics series).
