Here is an explanation as to what is happening in the video :
Firstly my right hand controls the xyz coordinates of the cube.
My left hand y position controls the rate the cube spins, it also controls the rate of a low frequency oscillator controlling the cutoff frequency for the synthesizer you can hear in the video.
My left hand's x position controls the hue for the cube.
My head's Z position controls the feedback effect on the cube and also the pitch for the oscillator generating the initial sound.

This is how it was achieved : I made this using the synapse kinect application and several maxxforlive patches (within ableton live) to convert my hands' and my head's xyz coordinates into midi control change signals. I then used the cc signals to manipulate parameters on a virtual vst synthesizer within ableton live as well as routing the same midi signals using iac (inter application control) bus to control visual software vdmx.
Within vdmx I had a quartz composer patch I created (in quartz composer) that had several published inputs (xzy coordinates for the cube) that were also controlled via these midi cc signals . In addition to this I also controlled a quartz feedback effect within vdmx with the cc signals.
