Just stumbled on a very cool iPhone application called HearPlanet. Based on your current location it generates a collection of informative audio tours explaining the things around you.
As you can see from the attached screen shot, it found quite a bit of information about the Horse. That seemed surprising until I understood how it works.
The first thing HearPlanet does it identify your location by using the iPhone’s built in GPS. Then the app draws down information through the internet from Wikipedia articles about locations nearby you. A built in text-to-speech engine reads the words out loud.
Quite a simple premise, but very well executed and easy to use. It seems like a cool app to travel with and keep yourself informed about each locale you visit.
Normally $4, HearPlanet is free on the iTunes Store right now.
