Doritos teamed up with several agencies (e.g. Mekanism and Proto) and Blink182 to present a concert on a snacks bag. In fall 2009, on www.doritoslatenight.com you could hold a marker printed on a Doritos bag into the webcam connected to a flash app that would recognize that code and put a concert video by Blink182 filmed in a green screen room into the virtual space. You could than turn the bag and thus control the perspective of the video. Great brand transfer and well done technology of “musicians in your palm”.
Here is an example, find the making of video from a more detailed Wired article further down.
