there's a guy called UKKO that has a mat called 'USS Derelict'..that works in a pinch..used to be in free stuff..it's not always available, but it's handy when you want something like this..I think some small bits of things floating around, maybe some bright and dark spots (there's a scene in Starship Troopers something like this..great stuff so far..

I wish I'd said that.. The Staircase Wit
