I have an amibilight built around WS2812 LED strip and esp8266. I use it to display a colorful rotating gradient during a day and as a night light with red color. Small Haskell program using reactive-banana-automation feeds simple nodemcu firmware every second with UDP packets. It's quite easy to build RGB light this way as only one signal wire is required.
