The iPhone gaming has come a long way in the past few years. As the iPhones get better, developers find new ways to make the gaming experience on these tiny devices more fun. TheO is another nice idea for iPhone gaming. It is nothing more than a foam ball but keeps the phone in the center of the sphere and would work great for games that require active movement.
At the moment, 3 games are working with this toy (Hot Potato, Interrogo, and Bowling). TheO ball is designed to protect the iPhone as you play with it. A pretty neat idea to bring more fun to iPhone games.
