I'm primarily a programmer and always have the same issue when starting new projects: I have no artistic bone in my body. But you can't always afford an artist.
What resources can I use for graphics? I'm primarily looking for free 3D models in various file types. They don't have to be elaborate, but should work for rapid prototyping.
Some years ago, for the GameDev.Net "Four Elements" contest, I compiled an extremely large list (link leads to WayBackMachine now). I haven't revisited it in some time, so probably a fair few dead links, but I'm sure there's quite a lot of live and kicking links too. It starts off with a bunch of technology links, but just scroll down. There's plenty of models and textures links.
