In this TouchDesigner tutorial we look at how to create a basic interactive particle system by using the Kinect v2 (works with Azure too), Optical Flow and particlesGPU. We especially have a closer look at the particlesGPU, so you can easily customize the look and behaviour of the particles to your needs.
