Random games concept art

Hey ! I don't know if this is the kind of thing that you are looking for but there is this tumblr (Managed by a member of polycount, I think ?): http://fuckyeahconceptart.tumblr.com/

A little bit of everything, from AAA games, some personal works of concept artists, some concept arts from movies too.

I also found this one in my favorites, but it is not really nice to browse, with only a handful of concept art per page: http://coolvibe.com/

Creative Uncut is pretty good and well organized: http://www.creativeuncut.com/game-art-galleries.html

My mate made this site:

Say your mate that he did a great job, concept root is my favorite!

Had a quick look at Conceptroot, great site! but it's annoying that pics aren't captioned saying to which project the art is related to (at least for the stuff i flicked through)

Does anybody know of any Wolfenstein 3D concept art or textures? Or any maps that are available on the classic game?
