Musical Dance Interface
An interface that allows users to create music by dancing. Possibly by allowing users to loop sounds created by rhythmically stepping on a sensor pad. The Kinect could also be used to measure movement and translate it to audio.

Exploring Hand-Centric Interfaces
I’d like to build an interface that takes advantage of the abilities of hands besides those currently required by computers and touch screens.
