It's stunning what you can do with drones. My first experience with these mini drones that light up was at a Metallica concert a few years ago.
For April Fool's, this guy who appears to own a company that does these types of drone flights programmed a flight where 300 drones formed a glowing QR code that when scanned, leads to the video of Rick Astley's Never Gonna Give You Up.
I tried it myself and it works even from your computer screen.
He did this prank in Dallas last Friday and lots of people were surprised to see the result.
