John Mayer Video Adds Each Fan As A Digital Extra

Augmented Reality Comes To Music Videos 

The new John Mayer video uses a bit of digital trickery to insert the fan watching into the background as an extra. Fans turn on their webcam and hold up a printed or mobile version of a special icon. That triggers the start of the video with them in the background. Via Music Alley above is a rough video from a fan showing how it works.
