While we wait for those Microsoftees to pull it together and get real with a shippable version of Surface, we can enjoy the valiant efforts of modders like Xylomn. This guy built his very own touchable coffee table PC with a 24-inch display and a ceiling-mounted camera for tracking hand motions. Since it's part of his dissertation for his software engineering degree, Xylomn also worked up some custom software which allows users to beam media to the PC via Bluetooth, and then geotag it on a touchable map. The table allows for multiple users at once, and the interface part of the software rotates automatically towards whoever is grubbing up the display at that point.
