From Rogaland county, Norway: "4000 Bus Stops that Tweet, Record Stories and Provide the Time of the Next Bus via QRCodes" (digitalurban.org)

Today sees the launch of our latest collaboration via the Tales of Things project - this time with a Norwegian transport company, Kolumbus. Tales of Things has been utilising Kolumbus’ already existing QR codes to allow passengers to leave stories for one another. When a passenger visits one of Kolumbus’ more than 4,000 bus stops they will find a QR code which when scanned with the free Tales of Things’ app on with the iPhone or Android it will not only link them to timetable information, but also allow them to leave a message on the bus stop.
