5 of the best quirky QR codes – Facebook's rooftop QR code

Facebook recently turned heads when its staff painted a giant QR code onto the roof of their brand new headquarters in California. The 42-foot-wide code was created as part of Zuckerberg’s ‘Space Hackathon’ (the staff took it literally) and links to the FB QR code page.

Facebook wasn't the first to come up with the idea, though. Many companies before them have created giant QR codes that can be viewed from several miles up. Some have even been purposely constructed so to show up on Google Earth. Sure, the code takes about a year to show up, but that’s still some pretty sneaky marketing.
