iPhone Controlled RC Car using an Arduino

Here is another cool iPhone projects that controls a RC car. Is the iPhone the new Swiss Army knife of portable electronics?
"Controlling is very easy with the iPhone 3G. It has five buttons, four of them you can use for traditional &bdquodriving&ldquo and when you press the last one, it unlocks the accelerometer control in the same way as in many driving games available on AppStore. Realization of this project did not take a long time, only one afternoon. Technically it is realized in a hell-bent way, but obviously it’s functional. Schematically: iPhone (OSCemote) → WiFi → PC → Max/Msp → Serial port → Arduino → Original controller."
