This commercial building in Tachikawa, Japan, has a QR code designed on the outside panels allowing cell phone users to take a picture of the 2D barcode (similar to Blackberry Messenger & other apps) and be directed to the building’s website.

Also users with an additional app installed on their device (available via iPhone), can aim their camera towards the building and be greeted with an augmented reality layer over the building, showing a more interactive display of the building’s stores, their sales/promotions, and even showing tweets from within the building.
