If you have never checked out the Enlightenment Desktop Manager here's a perfect time to take a look. The Elive project just released a new version today of thier liveCD containing Knoppix with Enlightenment 17.
As of right now there is only a torrent for download, but direct download by ftp is coming soon. But the torrent was very fast for me. I downloaded the 645 meg iso in 26 minutes.
