It was created by Jonas Jäger, and more importantly, he doesn't plan to keep the technology to himself. Jäger plans to release a front-end application that will let you create your own "presentation" that will be displayed when your business card is flashed in front of a web camera. It uses a QR code to identify your card from others, and an AR marker to have FLARToolKit something to get a fix on. All in all, it answers Thomas Carpenter's call to create a service for these kind of augmented business cards, and really looks good.
