In Japan(where else?) interactive designers have been messing about with QR codes, LEDs and augmented reality to make city centres more engaging. None of the technologiesthey’re using are revolutionary, but the application is.
The NBuilding in Tokyo is a great example of this. It's covered in QRcodes, which means when you view it through a smart phone it tells you allabout the shops inside: what's new, what's on sale, what’s on offer, and evenif restaurant reservations are available. But that’s not all, you can also seethe Tweets and comments of the people inside, thanks to Twitter geotagging.
