I get dizzy when I look at this prototype. It was never built. Mostly part of a Usability exercise to determine how much information we could visualize on the map by using more complex artifacts.
We decided to move on a different direction, but technologically speaking we had all the elements needed to produce these visualizations. This was the beauty of working on flash... no restrictions on how complex the visuals were.
It reminds me of those "infoporn" charts that you find in some magazines.
