I did these for the upcoming Next Action event at SMOCA.  This is 10 seconds of high school students expressing themselves with their hands and head motion captured on a Kinect, then rendered in 3D.

Kinect data visualized in Cinema 4D.

Red = right hand.  Green = left hand.  Blue = head.

Tiny V-12 engine!

C4D/Python/expressions.  This is pretty fun.

Rendered this out using Depth of Field (which they changed in C4D R13.)
