Mike Kuniavsky hacked a cheap 3D mouse to turn it into a "magic wand" that controlled his Mac by means of gestures, and wrote a great article about it, describing the build and covering what it feels like to drive a computer with a magic wand:
Quicksilver's gesture recognition software isn't the best (it's not like the IBM SHARK stuff I described earlier), but it's better than other alternatives that I've seen. And, because it works with Quicksilver, that means that there's a large library of knowledge about actions that can be triggered with the gestures. To me, the most interesting possibility, and one that I'll be playing with, is that Quicksilver can issue arbitrary commands, including command-line input to software that can control things back in the "real" world. Command-line input to Processing or NADA, for example, will allow easy magic wand control of things like, oh, Roombas, lights, giant mechanical beasts or teleporters. Hide the computer, disguise the mouse, and action at a distance is yours. Kinda
