Lots of work as you all know very well and it was VERY disapointing.
I expierenced the opposite of your disapointment. Just half way through putting up the lights on my house I plugged it in to see what would happen, since this was my first year doing amimation with music. I was beside my self that it actually worked. I still go out and watch by my self and still amazed that I put this display up. I live at the end of a cul-de-sac so there is no traffic but one night I was out there and one of the neighbors walking thier dog said to me that our display was like a gift for the neighborhood.
