Kinect OSX Flipped Curser Control

 * SimpleOpenNI Hands3d Test 

 * Processing Wrapper for the OpenNI/Kinect library

 * programmed by Sam Hessenauer, start Date: March 2013
 
 Based off of Max Rheiner / Interaction Design / zhdk / http://iad.zhdk.ch/
 
 * ----------------------------------------------------------------------------
 * This demos shows how to use the gesture/hand generator to control a mouse in 
 backgrounded applications, with the right side of the screen being a click.
 Next steps are to add gesture recognition to simple click, right click, and hold click.
