I've known the founders John and Kwin for a few years, so here's a few more details: - It really works. The key difference between this and other gestural interfaces is that it doesn't require any markers, just a couple of video cameras. The magic is in the processing, they're able to get millimeter-accurate positioning from your fingers. That means you can use your finger like a laser pointer, even for delicate work. I spent some time using it two years ago, and it just all works. - You don't have to get gorilla arm. One of my first concerns was holding my arms up, since I suffer from RSI. It works fine with your hands by your sides. - They self-funded for a couple of years getting a prototype working, then got VC from the Foundry Group, Brad Feld's firm.
