"Imagine bubbles floating before your eyes, filled with cool info about stuff you see on the street". No, National Geographic isn't describing the first signs of a stroke, but showing us the way we might soon be experiencing the world through augmented reality (AR). 

After downloading software, smartphones can use built-in GPS, compass, and camera to find information about nearby ATMs, restaurants, transport, and other points of interest. 

No matter where you stand, your smartphone will even be able to tell you who's Twittering in the area, where the cheapest take-out is and when exactly a statue was designed.

Makes current executions of AR look pretty weak.
