For the iPhone or iTouch with camera, there is now a great Augmented Reality shoot-em-up based on the Death Star attack from Star Wars. Tech Crunch gave the word about Falcon Gunner, and it does look like silly fun. Of course, you might want to consider carefully where you want to play this in public. This is the first of what promises to be a whole series of Augmented Reality games coming from Vertigore, and since they did the licensing deal you can expect the first chunk of them to live in the Star Wars universe.
