Macworld has an article about a new offering from Metaio that excites me: image-basd augmented reality. The whole idea of augmented reality is so cool: point your phone's camera at something, and when you view the live image on your iPhone you'll see related information or content superimposed on that image. Think of how useful this would be to tourists: you point your phone at the Eiffel Tower, and your phone superimposes information about it. Augmented reality has already been available, but it was GPS-based.
