iSpy is a modern twist on the popular game, 'I spy with my little eye...' for the iPhone. Each game contains a picture of an object you need to find in the real world. Players earn points by finding the object and taking a picture of it.
Launch the game in your iPhone and a list of iSpy games around your location is shown via Google Maps. Each game features a photo of the object you're looking for, a map and reviews from other players who solved the game.
To create a game yourself you just need to take a photo of something and use the 'create screen'.
The iSpy website also features a real-time Google Map that animates through information windows showing news of who has just completed or created an iSpy game.
