GPS Puzzle Box

MapHere’s an interesting concept: a GPS-aware box that will only unlock when it’s at a specific location. It includes a button that, when pressed, tells you the distance to that location. Even though it would only take three readings to get a rough estimate of the location, I still think it’s a neat idea.
