A company called Ars Electronica has developed what’s called a Spaxel. These computer controlled drones can ‘draw’ some amazing things in the sky! Spaxels (a portmanteau word from space pixels) are LED-equipped quadcopters. A swarm of LED-equipped quadcopters that can fly in precise formation and thus “draw” three-dimensional images in midair.
My first thoughts were as I watched the attached video was how this technique could be used to make some fantastic UFO pictures. As I look at the amazing examples of Spaxel’s I can see how it would be easy to confuse one of these works of art for a genuine UFO.
