OK I was just reading the discussion in the random texture thread and it sparked the idea to create a contest for making good looking clean textures =)
So go ahead create anything you want, just make it clean. How clean you ask? Well let's do it like this.... you make the texture and you tell us in what kind of location we'd find the texture.... like if you made floortiles you could say "floor tiles for a hospital"... that way its easier to imagine the texture in an environment. You can also render the texture with spec, normals and so on if you want to.
This should be interseting!
