GPS-Locked-Treasure-Box
A box that stays locked till it is taken to a specific location
####Description
This puzzle box was made as a present for a cousin's wedding. The sole purpose of this box is to take the newlyweds on a a number of 'quests' to locations that are important to them. Once they have fulfilled all their quests, the box opens to reveal a small gift inside - however, as in life, it is the journey that counts, not the destination. :)
Once opened, the box will stay open unless reset, and just count up from the wedding date and display the time elapsed since the wedding every time it is activated.
