The Kraay family in Lacombe, Canada has broken a Guiness world record for the largest "QR" computer bar-code, and it's made out of a corn field. 

The maze covers 7.4 acres. 

The CBC news in Calgary reports that the family proved it works, by flying over their farm in a helicopter and holding a phone out the window.

The Kraay's code directs people to the website for their mazes.
