There is a lot of talk over at Minimal Mac about a spartan desktop. I do recommend Minimal Mac for its links to invaluable OS X tools. However, I frankly don't understand the whole fuss over an empty desktop. I never see my desktop as it is always covered with windows. Nevertheless, I do have a desktop background image that I took from the fantastic set of images of textures at Bittbox. Every now and then I see it because I press F11 to show the calendar I have embeded on the desktop using GeekTool.
