Finding Yourself With Photo Recognition

itchyfish writes "You are lost in a foreign city, you don't speak the language and you are late for your meeting. What do you do? Take out your cellphone, photograph the nearest building and press send. For a small fee, photo recognition software on a remote server works out precisely where you are, and sends back directions that will get you to your destination. Seems a little far fetched, but amazingly cool if it really works."
