'Clutter' your desktop with album artwork

Clutter by Sprote Rsrch.: "Clutter is a small Mac OS X application that lets you put music CDs on your desktop. You can drag them anywhere -- they're really windows. Line them up neatly or put them in piles, it's your choice. Each one looks like the real CD's cover, and double-clicking it tells iTunes"

The recent update of this fun little bit of freeware seems to work quite well - a fun addition if you have lots of songs and album artwork.
