QR codes seem to be sneaking off of subway ads and into our built environment. The Russian Pavilion at this year’s Venice Biennale was covered from dome-top to floor with codes giving a glimpse into future Russian cities dedicated to science. And a hotel room at the Hotel Modez in Arnhem is also covered in the black-and-white symbols – including custom-made curtains and bedspreads. And the AIA of Tampa is promoting information about the city’s best buildings via a QR-code tour – with 23 sites displaying the codes.
