SPARKED A Live Interaction Between Humans and Quadcopters

It's not magic,it's drones!!
Quadcopters join the circus,in this magical video from Raff D’andrea And Cirque Du Soleil.
The quads are attached to lampshades with high-power LEDs mounted inside, and they use an algorithm to determine roughly how to execute the choreography. The quads run custom software for estimation and control — but they’re flying completely autonomously.
