Every five minutes, Tumblefile copies all files on your Desktop to a folder such as ~/Documents/2009-07-July/25-Saturday, prepending a timestamp (like 20090727.1645) to the filename. Meanwhile, its little window sits in the system tray. It is a way to automatically keep your Desktop cleared and files organized.
