I don't have the equipment anymore to maintain this project. Please have a look at tuffnerdstuff's fork, who kindly invested some time to address some of the open issues.
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).
- 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
