Laser Christmas Lights
Today my wife brought home a "Laser Chrismas Light". On the ground it is totally cool, lighting up the house in multiple colors in seconds, and eliminating the need to spend hours on the roof stringing conventional Christmas lights.
When I got it positioned, about a 2 minute process, 3 different neighbors came over to ask where she got it. I think these things are on the path to go viral, and I can't imagine the distractions of flying an approach over a city filled with them.
