The detail that caught me off guard is the scale: fifty light-show drones flying in formation above a single family home in Keller, Texas, for Christmas 2021. This was not a hobby experiment either. It was flown by a professional drone light show company operating under FAA waivers, and it was the maker's own stock 50-drone Christmas show, brought home for friends and family after flying shows across the country.
The ground side is a proper display in its own right. There are illuminated lawn cones, large conical mega-trees, and oversized candy canes along the walkways. The bulb strings carry individually addressable multi-color LEDs, and the lawn also gets glowing white-and-red candy cane stakes, small lit cone trees, and spotlights aimed at the house facade. The pixel lights were arranged in custom formations and programmed in xLights, which is the same tooling many of us run for our own sequences.
The coordination is what stands out. The drones launched at once as a synchronized green grid, then the ground lights chased, flashed, and shifted colors in time with the aerial elements. The aerial figures covered a lot of ground: a wreath, holly sprig, animated gingerbread man, stocking, hanging ornaments, top-hat snowman, snowflakes, a star, a spinning tree, and a Santa hat, plus a multi-tiered tree with an orange star over the roof. Afterward the drones turned purple and settled back onto their launch coordinates in rows.
One open question for me: the swarm control hardware and software, the drone models, and the lighting modules are never identified, and the controller boards and power supplies behind the ground lighting are not shown either. I would love to know how the ground sequencing ties into the flight choreography. In my view this is the most ambitious residential holiday display I have come across on this forum.
