Check this out, I saw the pic that Templarian posted and remembered that a while ago I had an updating wallpaper thing:

It updates itself every minute (or however long you specify) so you get a live (kind of) picture of what earth looks like from space! It even has clouds and stuff…
I think one of the images used in it is actually the one Templarian posted.
