The only thing impressive about this is the demo itself, showcasing some fun physics and you can draw your own "bodies", but while they're using kinect for that, they could also be using a wiimote or move which would result on a more accurate and drawing. the only thing used here are pointer controls, which can be done better on wiimote or move because the nature of the controllers themselves against kinect.
There's nothing "kinect only". It just shows that kinect can also do it, but the lag on the pointer controls are completely noticeable.
As for the app, there's a DS game that simulates physics too... Dr. Wolfs something. So it is nothing spectacular and unique either.
How do you open and close your hand with a Wiimote / move controller? shake it?
this educational video should explain everything especially at 0:48 onwords
