Muddiest Point (8/31/09)

This is more of a request for more information than clarification:

I had a chance to look at the "Visualize the Collections" or "Bungee View" prototype for the Historic  Pittsburgh Image Collections website.   Are there any other visualization tools like this one that we can look at on the web?

Which aspects of Bungee Viewer are representative of emerging technology? Is it in the components or the way the capabilities are bundled into one package?
