A swarm of drones dance across the night sky as an orchestra plays Beethoven's dramatic "Fifth Symphony."

It may sound like the heavily-CGI'd intro of a sci-fi movie, but Intel Corp. actually pulled off the spectacular stunt at the Ahrenlohe airfield in Tornesch, Germany last November.

The tech company's ground crew controlled the drones using PCs running Intel software, syncing their flight and light display to the music performed on the ground.

The feat earned a Guinness World Record for the "Most Unmanned Aerial Vehicles (UAVs) airborne simultaneously."

Intel CEO Brian Krzanich showed the footage for the first time during his keynote speech at the CES technology show in Las Vegas last Wednesday. It was posted to YouTube on Friday, and is now going viral.
