Upcoming Tutorial: Kinect Skeleton
Coming soon, a tutorial on generating a SOP skeleton from Kinect CHOP data. You can use this to create all sorts of generative characters when you can't (or don't want to) use a rigged 3D model. This generative model also serves as nice source geometry for particles, instancing, etc.

Examples of the technique:
