Today I released Tilt Racer, an app that lets you use your phone as a steering wheel with nearly any driving game for Windows. You tilt the phone to steer, and use a unique split slider to control the throttle and brakes. It communicates over WiFi with a server app on the PC. The server emulates a joystick, so it works with nearly any game that supports joysticks or steering wheels.

If you remember FlyPad from YC, it's a bit like that, except that games don't have to explicitly support the app. It just works with hundreds of existing games, including the most popular racing simulations like iRacing, rFactor, and Simraceway.

The app was built with HTML5 and PhoneGap, so it works on iOS and Android (4.0+). I'm the sole developer, and put this together in my spare time while working on another startup.

The graphics are basic right now, but I plan on creating some awesome skins for it, so stay tuned.
