A drone light show staged in celebration of a video game ended with the drones forming a massive, scannable QR code in the sky.

Anniversary celebration: The drone light show was held in Shanghai to commemorate the one-year anniversary of the Chinese release of "Princess Connect! Re:Dive," a Japanese role-playing game.

The game's developer, Cygames, collaborated with Chinese video-sharing website Bilibili on the show, which featured 1,500 LED-equipped drones.

After forming a smartphone with the game's logo on its screen, the drones flew into the shapes of three game characters, who then battled — and defeated — a dragon in the Shanghai sky.

The drone light show ended with the QR code — scanning it downloaded the game onto users' smartphones.

The future of marketing? This is hardly the first drone light show.

In 2012, 49 LED-equipped drones took to the Austrian sky to wow attendees at the Ars Electronica Festival, and since then, they've been incorporated into Olympics opening ceremonies, election celebrations, and several Super Bowl halftime shows.

We've also seen examples of LED drones being used for marketing before, but this is the first known instance of a drone light show forming a scannable QR code in the sky — giving viewers a way to connect with a product immediately after the lights go out.

Yes, drone racers are a thing and they’re amazing. The Drone Racing League has gone from a dream to ESPN in a few short years. We met world champion Paul Nurkalla, aka Nurk FPV, and got an inside look at how the DRL is striving to be the next big sports league. Somewhere between esports, NASCAR and Star Wars sits drone racing, also known as FPV racing. It’s a breathtakingly fast spectacle where drone pilots fly quadcopters...

Drone technology is fundamentally changing the way we respond to natural disasters. In the aftermath of Hurricane Harvey, rescue teams used drones extensively to map and triage affected areas, while utility and cellular providers used them to inspect damage and prioritize repairs. Cheap to operate and with the ability to cover widespread areas, drones are changing the game when it comes to cleaning up disaster zones. ...
