Are These UFOs? Nope They’re Spaxels [VIDEO]
Flipping through the TV over the weekend, I stopped when I saw what looked like a swarm of UFOs hovering over a major city skyline. At first I thought it was CG that brought the lights to life. Boy was I surprised when I discovered what I was seeing.
A company called Ars Electronica has developed what's called a Spaxel. It's a combination of the word space and pixel. These computer controlled drones can 'draw' some amazing things in the sky!
