Got any Gimp Textures?

Hi, anyone know of any royalty free for commercial use textures to use in Gimp? In mean the sort of ones you can do a fill with. I've googled but get lost in a quagmire and figured some of you might have decent links.

I'm particularly looking for cool techno-esque backgrounds, sorta like the level backgrounds in rtype (but better quality). Thanks in advance :-)




Also something vertical, maybe with lines on...

try turbosquid.com

Groovy thanks tim, found some cool free textures, although no small print that defined "free", so I'm gonna assume totally free ...
