N Building from Alexander Reeder on Vimeo.

Japan’s capital is becoming more and more digital – unlike the usual advertising hoardings and billboards, the façade of this Tokyo building displays a QR code to allow mobile phone users to access sets of information on stores, make bookings, download materials, tweets and animations that come to life on the screens of their phones. All in all a way of knowing what’s going on in the block down the road without having to visit it directly.
