I am selling all these terragen worlds ( i will resize for you) as desktops/wallpaper. Also if animated desktops/wallpapers are possible, i can make them too (by putting multiple terragen worlds together). If you want one, just tell me which one and offer a price and tell me the required resolution. They aren't great but i will sell them cheap. I can also put any text you want on it, just tell me.
