This tool utilizes kbinani/screenshot to capture your screen, computes average color values and sends them to an ArtNet node via jsimonetti/go-artnet. This makes it possible to set up an ambilight system similar to "Philips Hue" (if you have the spare parts lying around of course).
Disclaimer
should work on Linux, Windows and MacOS (though I only tested it on Linux and Windows)
not nearly finished, I still have some ideas and performance optimizations in mind
