Thanks! Our current gesture set is more focused on showing what's possible so far and inspiring some new ideas. Navigating the web is only one application of the framework we built - we envision all sorts of applications that run in the browser, from games to specific utilities for specific sites. The great part is that now web developers who specialize in Javascript can work with the Kinect without having to learn any special languages or code. We're hoping this allows a new set of interactions beyond what we first developed.
