3D Desktop Jigsaw Puzzle Screensaver - Watch as your desktop, or any other image you like, is broken up into a jigsaw puzzle and then slowly put back together again. The jigsaw pieces move around in 3D, and you can display any image you want!
Version 1.1 updates the screen capture code to work better with multi-display systems, and adds the option for you to select the detail level of your images.
