On Friday was the "Tag der Deutschen Einheit" - the national holiday of Germany. This year it was in Hanover and finished with the big laser / lightshow / firework as well as with a show using 30 drones equipped with multicolour LEDs and autonomous positioning capabilities. The whole show was recorded by a local TV station and can be found ->here<- (embedding video was not possible). The interesting stuff starts on minute 29!
Anyone knows which setup the team used?
