Have you ever thought of playing a guitar with a mere piece of paper? Intel Brazil published an ad in the Rolling Stone magazine that allows the reader to use the ad page to activate an augmented reality application online in which the user can do both play the guitar and use a Dj mixer virtually. All you need is the Ad from the magazine, and a webcam to play the instruments.
A video demo of the Dj app is available here: http://www.youtube.com/watch?v=-R7JgoTRwLI
You can have fun trying it out yourself at: www.intelmusica.com.br
