I like this program.  Stardock Fences will organize your icons into… well… fences.  So if your the type that has a lot of desktop icons then fences is certainly for you.  The best feature is the ability to scroll through icons in a fence.  If the number of icons fills up the space you allow for their corresponding fence then a scroll bar appears when you hover over the fence and you can scroll through them.

Pictures speak louder than words, no?
