This video, which came out only a week ago, has already gotten more 4 million views on YouTube. And it’s easy to see why. They’re nano quadrotors at the GRASP Lab at the University of Pennsylvania.

Of course, the flip side of that is seeing a swarm of mechanical flying things coming at you in formation is just a little… unsettling. Just to play it safe, let’s not piss them off.
