Deviant Art is a plethora of creativity. The link is for a search of wallpapers. Under each piece is a subcatergory. So if you only want photo wallpapers or abstract, you can find what you want.
Cute, weird, and fun. These are 200x200 squares meant to be tiled for your wallpaper. Click on any of the pics, then click on the black and yellow arrows to open the tile for downloading.

Weird. That's the best word for most of these wallpapers. But cool too.
Beautiful nature wallpapers beyond typical beaches.
