Rearranger for Mac

From Sean P. Carapella:

Rearranger is best best experience when placed in the Startup Items folder of an unsuspecting freind/co-worker. On startup, Rearranger launches and then moves itself to the background. After two minutes, it starts to rearrange (hence the name)the all of the items on the desktop while also randomly changing the icons labels. It will continue to change the locations and the colors of the icons every minute or so until quit.
