I have spent many hours of learning and playing to get this [mostly] right and I am pretty happy with the final results. I put together a light show on my house for Christmas and a little write-up of why I did it and why it is important to me. This whole thing is done with Linux. The controller system runs Linux and I performed the sequencing on Linux, openSUSE to be exact. This is my first go at such a thing and I hope to improve over time.
Or on YouTube Directly if you don’t want to see my blathering about it.
