You need a fairly good computer so it won't slow down too much if you have many aplications runing and the animation of your desktop.
It's a program that makes your favorite (any) screen saver run as your desktop all the time. You can disable the normal screen saver and run it as your desktop trough this program.

Just beautifull.
