Will your next drone be a butterfly?
The German company Festo, who specializes in bio-inspired robots, had demonstrated the ability to fly a flock of butterflies. They might not be as beautiful or colorful as real ones, but the technology has certainly potential! Look at the video and see how the butterflies move around. They were actually controlled externally, by cameras and a central computer, but that does not detract from the elegance of this experiment [ source: popular science].
