Windows Longhorn is supposed to sport the ability to turn the desktop into a 3D environment, allowing you to not only minize windows, but to place them in the background or foreground, one in front of the other. There is a program that will give you the ability to do this now, though. That utility is Spaces.

“Spaces is an innovative new product for today’s personal computer. Spaces unleashes the graphics power of your PC with a new and expansive workspace. Spaces allows you to manage multiple windows efficiently by allowing applications to recede into the desktop onto a user selected workspace. Point, Click and Drag to organize and recall the windows visually. Image files dropped from Explorer or a Web Browser onto the workspace open automatically. It that’s simple. The environment can be fully customized to the user’s preferences. Spaces provides dynamic animation and physics based effects coupled with panoramic image viewing.”
