This is clearly one of the best ads I have ever seen. ecko unltd., the company which some of you may know for selling clothing mainly targeted at the hip hop demographic, is responsible for this billboard which allows the viewer to put his own graffiti up on the LCD screen of which the ad consists. It works over Bluetooth and is supposed to show the founder's (Mark Ecko) roots in the graffiti scene.
It is really a great idea in my opinion especially because it will force hordes of people to stand in front of the companies advertisement for a far longer time than they would with a normal ad.
