The Kraay family in Alberta, Canada, has created the world's largest QR code using a field of corn. When scanned, the code takes you to the family's website. The code can only be seen from above and only works when scanned from a helicopter (don't try scanning the picture.) As an added bonus, the family's QR code corn field also doubles as a maze. Should you get tired of walking through the corn maze, the family also holds pig races.

Don't be surprised if you see the record for the world's largest QR code wrestled away from the Kraay family in the coming months. Using crops as an aerial advertisement is a stroke of genius. Farmers around the world looking to make some extra cash may very well start planting crops to spell out messages or QR codes.
