Warhammer's a good inspiration, not like I get it anymore, although I see a thing and think, 'neat! that looks good...'
and draw something like it.
I'm working on my 12 alien species the Baron leads...
more on that later...

also i've found games like Fable good for inspiration, and picking random letters from Scrabble and messing around with them to get good names, games like Halo and Half life 2 are good for futurisic armour.
