QR Codes to Twitter

DDB set up a system that pulled in messages of love or hate from Twitter, they then put up QR code posters around Sao Paulo which when read by peoples mobile phones displayed one of the messages of love or hate. Their next step was to create an actual book full of these QR codes and sell it on the Editoras site, as with the posters people could use their mobiles to translate the QR codes to messages of love or hate. DDB made use of the fact that QR codes can simply provide links to online content and therefore you can change what information a QR code links to by simply changing the content at the end of the link. After every 7 days all the codes in the book provided different messages of love and hate, and ‘the living book‘ was born. (See video above for a better description).
