Just saw this project developed in UDK. One of the author is Tony ‘Scarface’ Seifert, a well know mapper in the community 🙂

From the authors:

This Ski game has been developed during our diploma thesis. It was the goal to connect the Motion Capture System of Organic Motion with the Unreal Development Kit. The MoCap is provided to us by our school HTW Dresden. It’s completely controllable without conventional controllers. Music by Endless Vacation.
