Now that you can (officially) connect the iPad to external displays with HDMI (using this thing), game developers are starting to work on games that use the iPad as the controller and outputs the actual game on a bigger screen. Real Racing 2 HD is the first, supporting up to 1080p (on the iPad 2) output after today’s update. When you have the iPad connected to a second display, the game will see this and start using both displays independently. The bottom display will show menus and (while racing) the map and various information displays, while the screen will show the actual game image in console quality (ish) 1080p. The iPad serves as the steering wheel as well, using the accelerometer to sense you turning it. All you need now is this DIY project and this cable extender (to stop the HDMI adapter from falling out if you turn too quickly) and you’re all set.
