Straight Nonsense : QR Code Guinness Glass
BBDO New York came up with a great idea of putting a QR code on a beer glass, but the catch is that dark(specifically Guinness) beer will allow you to access the code. Scan the code and it “tweets about your pint, updates your Facebook status, checks you in via Foursquare, downloads coupons and promotions, invites your friends to join you, and even launches exclusive Guinness content.”
GENIUS! Another reason to drink that deliciousness.
