Are you selling kits? I would like information on buying one.
No, sadly I stopped really working on the whole thing. I built a neat IDE, a mobile app, firmware, it was really sweet. But it's a hard market to break into. If you're looking for Christmas tree lights for next year (or just for fun) I think Twinkly make a good product
Yes, it runs simple program that uses rpi_ws281x + LuaJIT to run lua scripts (haphazardly written in web editor) that generate output data.
