The first idea was about making a piece of software for Rpi2 to directly control individually addressable LED strips. Then the idea to make a cute light fixture out of those LED strips came in. The remote control app made an obvious and useful add-on.
The software supports two types of LEDs - NeoPixel (WS2812B) and DotStar (APA102C) through slightly different hardware adapters.
The picture below shows two lights I made so far. The top one (LightStar) is made of NeoPixel LEDs, and the bottom one (LedPanel) is simple 8x30 matrix of DotStar LEDs. Each fixture is currently controlled by separate Rpi2.
I made a script demonstrating some static and dynamic shows, see the movie clip below. The script only demonstrates a few shows while controller capabilities are virtually unlimited..
