In the latest in an apparently ending series of tech ads that are also legitimately cool on their own terms, we present this video of a swarm of quadcopters touring a city, on their own, at night.

Yes it's a commercial by Lexus. No, they aren't paying us to post this. And no, we don't really understand the link to their cars either.

But you have to admit that watching a group of robots swarming around a T-Rex is pretty interesting.

Watch the clip, above - and then find out how it was done (and how much was real) in the making-of clip below.
