Ho, lee, cow. This video, a Part 1 demonstration of the amazing BumpTop, isn't just another conceptual touchscreen interface pipe dream; it's actual downloadable software, albeit only for Windows.
Watch the vid to see the well-thought out interface, and don't worry, the presenter's voice slows to a normal human pace after the first few seconds. The demonstration admittedly becomes a little less cool at 1:47--when it's revealed that you're working inside of a grey box that looks like one of the hospitality suites at Guantanamo--but even that can't detract from the freshness of the interface design.
