Having built my own lighting controllers for a similar display, I want to clear up a few points.
The power requirements of the modern LED lights are very modest. Keep in mind that the LEDs are not powered all the time; actually they spend most of the time turned off. For example, my 32 channel controller with lights draws about 50 watts.
As far as contributing to light pollution, the whole show is *much* dimmer than a single (horrible) wall pack.
My reason for doing this is that it's fun. It costs nothing for you to watch and I'm not trying to sell you anything.
