Transparent New York is lovely and amazing. (via Lesbarkeit von Strukturen)
Can we do this with site mapping? Should we?
addendum
After playing with it for awhile, I grew used to its tremendous beauty and because frustrated with it for its lack of information. To be beautiful (I suspect) some data was removed that would make it easier to understand. In particular, Animated Manhattan frustrated me– I felt there was knowledge just out of reach of my comprehension, and a tiny bit more explanation of what I was looking at, a referencing grid perhaps, would make all the difference.
