Did anyone even know what a drone was before this year? Drones, a long-standing military tactic, have been utilized across a variety of advertising campaigns lately (see how Coca-Cola did it). Austria's Ars Electronica Futurelab has found an even cooler way to use them. Their latest innovation, Spaxels, is literally flying light. This, ladies and gentlemen, is the next generation of advertising: flying light to create billboards on the biggest canvas imaginable. Embrace the future. It's coming.
