I would like to announce Harmonic Motion, a planned open-source toolkit for musicians and artists interested in working with gestural data (from e.g. the Kinect).
At the moment we're assessing requirements and plan to have a beta ready later this year. If you're interested in finding out more, we've got an infrequent mailing list where we'll send announcements here: http://harmonicmotion.timmb.com.
Also, if you are interested in working with gestural inputs and have a couple of minutes to fill out a quick survey on the website, that would be amazing. The clearer an idea we have of potential users, the better we can target the project to ensure it's useful and user-friendly.
It's being created at the Centre for Digital Music, Queen Mary University of London.
