Being hardcore fans of many science fiction shows ourselves, we immediately drew our inspiration from the mapping drones in Prometheus, Kinos in Stargate Universe, IT-O Interrogator drones in Star Wars, and many many other movies to unanimously decide on building ourselves a spherical shape drone.
SF fans of course recall the recent movie >I>Promethius, and it's extremely cool fictional flying spherical mapping device.
