This experience is paired with the AR Glow Stick painting experience.

The magic particles used the Microsoft Kinect depth map, meaning that the further away from the camera the fewer particles would generate and the closer the more particles would generate.  Any movement was tracked through the depth camera and particles would be illuminated from the participants.  Using Touch Designer, I was able to have the depth map by the force of the particles, in other words, when the camera picks up a figure particles will sparse out from the figure and move with the figure with rainbow colors.
