Books: almost everything by Terry Prattchet, Neal Stephenson and
William Gibson (almost, because I still haven't read everything).
And recently, I've added Charles Stross to the list, his "Laundry
Files" books are incredibly funny and entertaining.
Music: too much to list everything I like here, and it's almost
always in flux. Details can be seen at
Food: Hard to say, there's so many tasty stuff: Italian, Indian,
Japanese... never mind all the different regional delicacies here.
(Mmmmh, Brezn! ;) )
Movies: The one that I can see again and again is "When Harry met
Sally", I can never get enough of that movie.
