iPhone controlled R/C car [english]

It's still not even a week since I bought a new iPhone 3G and during this time my brother and I did a lot of cool stuff. The iPhone with its accelerometer and multitouch display is ideal for making gadgets. When I got it home, we started thinking about some cool demos which we could make. Incidentally we found an old R/C car model ;-) Have you ever seen anything like this? I hadn't :-) Did you ever think that an iPhone could do this? Enjoy!
