Wired magazine did an interview with both John and I.
Most AR you hold a marker up then the animation starts.  I thought it would be kind of fun to when you hold the marker up seeing your reflection while looking in on John's studio apartment then push through to the controlled environment.  Kind of seems cheesy now, but then it was pretty cool tech.
Some renderings of the heartbreak bombs that drop during his video.  The explosions of the bombs actually leave a heartbreak mark on the flooring after they land.
This is the marker I designed to trigger the augmented reality.  John loved the marker so much that it became the core mark of the John Mayer brand.  I see these vinyl stickers on cars all the time.
