I found this interesting, snippet from The Week:
Each drone is about a foot long square, weighs just over eight ounces, and sports a plastic and foam body to soften inadvertent impacts. They aren’t as flashy as consumer quadcopters, which is just as well, because you’re not supposed to notice them. Instead, you’re supposed to notice the four billion color combinations created by the onboard LEDs, and the aerial acrobatics choreographed with meticulous coding.
Each drone communicates wirelessly with a central computer to execute its dance routine, oblivious to what the hundreds of machines around it are doing. The system can adapt on the, er, fly, too. Just before showtime, the computer checks the battery level and GPS signal strength of each drone, and assigns roles accordingly. Should a drone falter during the show, a reserve unit takes over within seconds.
