I really don't mean this to be a self promotion, but I've been compiling a list of resources for game devs. I honestly can't remember if there is anything like that or not but you could click through graphics links and see.

Pixel Prospector also has another really great compilation as well. Might be worth a dig through to see if there is anything there to.

At any rate, if you find something like that, let me know please.
