Facebook Paints Giant, Useless QR Code on Roof of Headquarters

Painting enormous QR codes that are scannable from the air is something of a rite of passage for tech nerds—sort of like tagging a railway overpass in your hometown when you were a kid. Now, Facebook has gotten in on the action, unveiling a 42-foot wide QR code on the roof of its new headquarters at 1 Hacker Way in Menlo Park, Calif. When scanned, the code opens a Facebook fan page devoted to the code itself—a solipsistic bit of foolishness that perfectly mirrors some of the underwhelming aspects of QR codes themselves.
