Wired:

It’s probably the first time you’ve seen 300 drones flying in formation, but it’s almost certainly not the last. The technology underpinning the Intel Shooting Star drone system is fascinating in and of itself, but its potential applications are even more so. The same drones that accompanied Lady Gaga will one day revolutionize search-and-rescue, agriculture, halftime shows, and more.

I was wondering how they were doing it. I thought I was animation/CGI. Drones are way cooler, and a neat piece of tech that might be Actually Useful™ one day.
