Sound-reactive Kinect tracking LED wall

Sammy Kamkar created an amazing sound reactive LED wall

This 4×4 wall has 1,728 addressable LEDs and tracks anyone in front of it via Kinect. Samy does smart background subtraction by creating a “depth window” in 3d space as the Kinect can provide me full depth data. The software is a combination of code┬áhe’s developed in OpenFrameworks, Syphon and Quartz Composer for sound reactivity. The panels are driven by a $19 micro-Teensy board using Direct Memory Access.
