"PolyLight" LED backlight project. Software uses DXGI to capture framebuffer, averages the individual regions, then translates the frame data into a UDP packet. The packets are sent to an Ethernet shield on an Arduino Uno, which drives a series of WS2812B 5050 LEDs. The system is powered by a 5V 100W DIN rail mounted PSU.

The movie being shown is Blood Diamond (2006). Copyright Warner Bros, media used for demonstration purposes only, no infringement intended.

This software has since been used to develop a much larger DMX-based installation, which was first showcased at NOVA 2017: http://novaparty.org/
