You know what would really blow me away? If someone came up with a way to convert a 3D polygon mesh into a drone's flight path so that it could render any sort of 3D object into a scene with timelapse lighting. Light rendering.
Intel has a solution where you provide the 3D models (static or animated) and they automatically generate flight paths for dozens/ hundreds of drones, each acting as pixel/voxel. Of course with collision avoidance between them.
