When the inevitable swarm of robot deathcopters launches into the sky to enslave humanity, it will look awesome.

That's the only possible conclusion to be drawn from this clip of 49 quadrocopter drones flying in formation in the Austrian sky.

The synchronised light show ("The cloud in the web") was created by Ars Electronica Futurelab and Ascending Technologies GmbH.

It featured 49 AscTec Hummingbird drones, each flying in perfect formation to make various shapes and effects.

Take a look, above.
