BumpTop the 3D desktop UI that always looks exciting has added multi-touch. There are a range of touch controls that allow you to use multiple fingers to pinch, squeeze, rotate, toss, pan, zoom, and even crop photos. From the video this looks awesome. To take advantage of this you’ll need Windows 7. And of course we don’t have too many devices with capacitive digitizers to really put this in play at the moment, and I imagine the team behind BumpTop is awaiting those as much as we are. Check out the video.
