If you’ve been to the Sony Building in Ginza recently, you might have stopped in the entrance lobby to check out these cards that you can pick up. If you take it over to the machine nearby, you can place it in the sight of an overhead camera in order to interact with the card! You have a screen in front of you, and as soon as the machine picks up the presence of your card, a 3D representation of the building appears in the area at the top of the card (where the grey and black spots are). Thus, tilting the card means you can view the 3D representation from different angles, and from that get a plan of the various attractions on all floors. You also use the printed buttons on the card (forward, backward, and enter) as an interface with which to navigate through the info. Whoa!
