Submission + - The Reverse Geocache Puzzle Box

whitefox writes: An enterprising friend of the bride & groom hands them a wedding gift. They unwrap it to find a locked, wooden box the size of a book with a small LCD screen and a single button. When they press the button, assuming a GPS signal is available, a message appears:

What follows is an interesting story on the creation of a puzzle box that will only unlock itself when it's in the right geographic location and its presentation to the newlyweds. A follow-up sequel to the story is now available.
