With this program you also have the ability to fling objects and watch them bounce, as well as to search for desktop objects. Additionally, you get access to an assortment of widgets, including one nifty item that will upload a picture to Facebook when you throw that picture onto the widget.

All of that fun, though, does exact a performance hit: Your PC will run noticeably slower when you use this program. Nevertheless, it's quite entertaining, and useful for anyone tired of their old desktop. BumpTop comes in Free and Pro versions. The Pro version, which costs US$29, adds more functions, such as the ability to use your mouse wheel to flip through all of the items in a pile. But you certainly don't need Pro--the Free program works just fine.

"Good fences make good neighbors," Robert Frost famously wrote--and this program shows that they make good desktops, too. Fences does exactly what it says: It fences off parts of your desktop and devotes them to certain things, such as applications, Web links, folders, recent items, files and documents, and more. That way, instead of having to search through your disorganized desktop for an item, you just go to the appropriate fenced area and find it immediately there.
