Drone Swarm Generates Smoke Screen for Huge Laser Displays

We’ve all seen drone displays—massive swarms of tiny drones, each carrying a light, that swarm together in carefully choreographed patterns to form giant (albeit very low resolution) 3D shapes in the sky at night. It’s cool, but it’s not particularly novel anymore, and without thousands of drones, the amount of detail that you can expect out of the display is not all that great. CollMot Entertainment, a Hungarian company that puts on traditional drone shows, has been working on something a little bit different. Instead of using drones as pixels, they’ve developed a system that uses drones to generate an enormous screen in the sky, and then laser projectors draw on that screen to create “the largest 3D display you have ever seen.”
