I found this incredibly amazing technology which is able to put a massive number of images together and link each image on a relational basis. it also has huge zoom in and zoom out capabilities. what this means for example is that you can view an piece of text on a book right from an individual letter that fills the screen and seamlessly zoom out to (say) view it from a 100 meters away.

this video describes it best.
