Thanks for the kudos.
This is a MadMapper question, so it is best to post in the appropriate section of the forum.
For the moment, we are working on a tutorial that will cover how this installation was made along with some basics about how to deal with electricity, Artnet, etc.
However, when we do stuff we tend to take our time in order to get it right, so I can't say exactly when this tutorial will be available.
however recommend you check out http://adafruit.com/category/41
as they have some kits that can assist you in working out some of the basics.
