3Desk lets you manage your applications more easily in a 3D desktop adding the third dimension to your Windows screen.
3D minimized windows will appear in three dimensions and transparent on your screen and have the ability to be flipped, zoomed, moved, and swiveled in almost any way you want.
T3Desk is lightweight and simple to use. Install and run the program. Configure it, if you want. Just open any application (example, your browser), you can see a small icon (see screenshot above) on the top of the window, click on it to minimize to 3D. You can drag and drop it anywhere on the desktop.
T3Desk works with Windows XP, Vista and Windows 7. You can download the program at source.
