This project is a component of my wearable computer project. The idea is to create a flexible command system that can be used while walking or generally not in front of a screen. It's very similar in concept to the phone-based menu systems, although it's designed for ease-of-access to commands, not ease-of-use.
Sorry they're not in an archive of some sort. I don't have time to maintain such an archive for all my projects.
If you know XML, the structure is simple enough. If not, it's still fairly simple to poke at the example until it goes.
