This document summarizes Amy Lee's presentation on using WS2812 LEDs and Fadecandy hardware and software to create colorful lighting effects. The presentation includes demos of controlling LEDs through Fadecandy to display patterns, layouts, and temporal dithering techniques. It also provides information on Fadecandy hardware specifications, communicating with it through netcat, running the Fadecandy server, and example node.js code to generate lighting effects. Amy Lee will be demonstrating her work at the Tenderloin Playground on May 31.
