BlindSquare makes you sense what's around you.
The only thing you need to do is listen.
BlindSquare uses GPS and the compass to locate you.
It then gathers information about the surrounding environment from FourSquare.
BlindSquare has some unique algorithms to decide what information is the most relevant and then speaks it to you with high quality speech synthesis.
