"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 to play that CD." I saw this mentioned on a few weblogs today, and after using it for a few hours I can honestly say it's the coolest app I've seen in a loooong time. I'm attaching a screenshot of my clutter pile to give you an idea of what it looks like in action; click the link in my sig for a more detailed review.
