Drones are fantastic photography tools. Unfortunately, they typically require someone controlling them, so it's a bit difficult to photograph yourself doing anything noteworthy. The Lily Camera changes all that. This drone-based system uses a simple tracking device to follow your movements, capturing the action in 1080/60p, 720/120p slow-mo, or as 12 megapixel stills. No controller required — just put the tracker in your pocket, throw the camera up in the air, and get going.
