Drones to me are usually the annoying things that you hear buzzing ahead of you at the beach or in a park, usually controlled by a kid or a manchild haha for recreation. I'm also aware that the military uses them in drone strikes. But I had no idea that drones were used like this!
"A drone display is the use of multiple unmanned aerial vehicles (drones), often quadcopters, flying in a coordinated fashion for public display. They are usually equipped with LEDs, and the display held at night. The first drone display was presented in 2012 in Linz/Austria, where the Ars Electronica Futurelab introduced SPAXELS (short for "space elements") for the first time. The displays may be for entertainment, where the drones may use flocking or swarming behaviour.
The drones may also be coordinated to produce images. Using this emerging technology, displays have been employed for advertising purposes as well."
Check out these wild areal artwork made by synchronizing 2k+ drones in the night sky. Will you be adding these to your next Christmas lights display haha?!
