Map Projections to moving objects in real time.
Uses the Kinect to track and locate objects. Might be overkill for this project since the table doesn't move. However might be cool to use in reverse to NOT project onto people who are interacting with the table: http://chparsons.com.ar/#camara_lucida
Kinect projector calibration
Another example that might be overkill since the table is static.
