Bumptop has been around as a video concept for a few years. Now this amazing desktop organizer with a physics engine underpinning the UI is available for download (PC only). The software allows you to bump and toss weighted objects across the desktop and organize them into folders or piles the way you would on your real-world desk. It also includes the ability to pan and zoom on images with all the gesture support you'd expect. While a touchscreen (multi-touch supported when Windows 7 ships) display provides a more natural interface, Bumptop also works with a mouse. Check the video after the break -- then hit up the download link below which we suspect you'll be frantically searching for after the video ends. Granted, we we don't want to spend
