I created a short video showing a little bit of the technology behind the light show. I know it can seem quite overwhelming and you need to know some about computers, networking, etc. A credit card size computer called a Raspberry Pi controls the whole show. It interfaces with a special designed controller card that sends all the controls signals to the lights. If you have questions I am happy to respond or point you sites that I learned from.
All the lights are the WS2811 type. You can Google this or I am happy to recommend some good sites.
The main controller is from www.falconchristmas.com
The software is free and will run on a PC or a Raspberry Pi www.xlights.org
