That is becoming popular. There was a local man who did his house to a melody of Christmas Carols a few years ago. He stopped after neighbors complained about the traffic (people could not even get into the neighborhood most evenings!) I think the Botanical Garden does one as well in one part of the Garden for their Garden of Lights display. The only reason I would not think it was real was the lack of movement in front of the camera of any lights or people. Kind of hard to stop those head lights.
