Swarm of drones for light show
Do you know what a spaxel is? It's a Space Pixel, or a pixel in a 3D space, a multicoloured luminous point that can fly, with free movement in space. To get one, you couple a LED light source to a drone. Or preferably many drones, to obtain many spaxels and create designs, the more points, the more spectacular. This was conceived thanks to the well-known international Ars Electronica festival in Linz. Austria, which for several decades has endeavoured to promote inventions that combine art and electronics.
