Levi Strauss-owned apparel brand Dockers is claiming a first with the launch of a shakeable mobile advertisement within iPhone applications.

The shakeable ad, which will be embedded in a number of popular free iPhone applications, uses the device's accelerometer technology to enable users to interact with the ad itself.

Entitled "Shakedown 2 Get Down", the ad features freestyle dance expressionist Dufon, who dances around the screen wearing Dockers Vintage Workwear Khakis.

Launching now, the ad will run for four weeks within applications such as iBasketball, iGolf, iBowl and iTV.
