ZooBurst creates interactive, 3D pop-up books. In addition to this, it can also be viewed in Augmented Reality mode with the help of a webcam. After printed a special paper from the ZooBurst site, the webcam captures you and "projects" your pop-up book onto the paper you are holding. While this technology is fledgling and not without its major flaws, it is still quite fun to play with, and really lends nicely to the concept of a 3D pop-up book.
