Dockers have come up with a unique marketing campaign to promote its latest line of Khaki pants. Simply called Shakedown to Get Down, it is touted as the world's first motion-sensitive ad, which comes with free apps on the App Store, and lets users watch a freestyle dance expressionist named Dufon from a dance group called Circle of Fire. In the ad, the dancer dances on the screen wearing Dockers Vintage Workwear khakis. To make the dancer change his moves the user needs to shake the iPhone.

The free iPhone app will be available along with many other free apps like the recently covered BMW Z4, iBasketball, iGolf, iBowl, and iTV.
