A few days ago I started to contribute some art for Vegastrike. I never actually have played the game, but so what? When I draw something I can try to draw something useful instead of something random, so I did some stuff on request for use in the in-flight communication displays:
this thread in the Vegastrike forums. I actually like it to draw stuff on request, since that frees me from actually doing any creative work on it and doing stuff for a project that isn't my own also make it easier to get things done, since perfection becomes far less important.
