If you have read J.K.Rowlings Harry Potter series (like who hasn’t?!), then you will know all about the amazing clock Molly Weasley - Ron's mum - has in her kitchen.
The clock is no ordinary clock (obviously!), and rather than tell the time it shows exactly where each member of her family is: school, home, dentist, quidditch, prison or lost to name a few.
It is so cool, that we think EVERY family home should have one on their wall; something that a 21-year-old superfan from Duke University clearly agreed with.
The student decided to use his technical genius and an old antique clock to make his very own version – who says you need magic.
His clock, he explained on imgur, knows exactly where everyone in his family is, thanks to pre-set information, and syncs with phones to determine their GPS location.
"Everyone in the family creates locational rules on their phones, and it updates whenever they enter a specified radius!"
Absolutely genius!
