You don’t really expect khaki pants to be associated with technology, but a new commercial for Dockers designed for the iPhone is being called the world's first motion-sensitive ad. The new ad will reportedly be inserted into free apps on the App Store.

The ad is called Shakedown to Get Down and features 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.

The iPhone user is prompted to shake the iPhone to start the dancer dancing around the screen with sound. The interactive ad will launch in early March and run for four weeks on the free iPhone apps iBasketball, iGolf, iBowl, and iTV.
