Back in 2012, the Ars Electronica Futurelab unveiled Spaxels, LED-equipped quadcopters that are used to create 3D light art in the sky. In addition to static and animated aerial displays, the Spaxels can — with long exposure photography — be used for aerial light painting. Most recently the Spaxels have been turned into Smart Atoms, virtually linked arrays of quadcopters that can be manipulated by hand like flying building blocks.
