After researching how to hook up the Kinect to OSX to use it with MAX/MSP I found this handy application called Synapse for Kinect. It has been developed by Ryan Challinor for an interactive dance installation at Burning Man Festival. It sends data via OSC Protocol so that it can be used among several applications such as MAX/MSP, Processing and Quartz Composer. You just have to start the application while the Kinect is turned on and connected and it starts tracking users.
I did not expect to make the Kinect running that quick and get it working simultaneous in MAX/MSP and Quartz Composer to play around with some fancy parameters just with my hands.
