TopDesk - Vista Flip 3D for windows XP

TopDesk is a software for Windows Xp , which emulates the Flip3D feature of Vista as well as Expose of OS X.
Flip3d is the new feature added by Vista in which it shows the thumbnails of open windows in a 3D arrangement whereas in Expose the thumbnails are arranges in a 2D arrangement over the desktop so that you can switch between windows easily.
In their words,

Switch Between Windows Faster Than Ever Before

TopDesk radically reduces the time you spend switching between tasks by giving you the ability to quickly find the window you want from a thumbnail view.

With a single key press you can instantly view thumbnails of all open windows, display thumbnails of windows belonging to the current application, or hide all windows to quickly access the desktop.

Its a good app, but the only problem is that it's not free :( . It comes for a price of $17 I've used it's trial version and i was impressed with the performance. Generally such application tend to degrade your system performance but surprisingly I didn't experience anything like that with TopDesk. Also it is light weight on memory,cpu consumption.
