Mostly now I apply creativity to functional things, like drawing something I'm going to build, then building it. I use to paint, and have drawn, and done a few mini's etc.
Last weekend I got a request to do some quick DnD maps that were not too 'dark'. So I did 4 in 1.5 hours. It was about process, speed, and getting it finished.
Currently building some timber shelves in the garage off a sketch I did last month.
Did some quake mapping, and textures years ago. Also did 'sigs' for players and 'weblogos' for local lans/clans.. free and fast. Did a couple skins. But I'm just a hack, not a pro artist.
