Ever wanted to take a peak at a stranger's computer desktop? Now you can download a program,"DeskSwap," from the Web that allows you to exchange your desktop for another user's -- well, at least in the form of a screensaver. This program-as-work-of-art takes a snapshot of another user's desktop and then uploads it to the DeskSwap server. Voyeurs will love the fact that all of the shots are candid.
