We started doing Christmas lights illumination 6 years ago. This year the show contains 9,500 color changing and synchronized LEDs. The tree went from 800 LEDs last year to 2,160 and grew about 5 feet :)
We added a couple of matrices on the column, and a hanging string of inverted arches and sticks, that, at night, seem to be magically floating in the middle of the front yard. Santa is visiting our matrix a few times a night, as well as other jolly characters.
The show is synchronized to music, that visitors can listen to by tuning their radio (not internet radio) to FM 92.9.
