Any good sci-fi/spaceship textures out there?

I've been searching for some decent sci-fi and generally silver-looking texture packs but have had no luck, is anyone aware of any wads out there which have some good sci-fi textures?

Lots of Doomy sci-fi/urban/Hell textures here.

Also, Epic 2 had some neat alien textures.
