Link: Transparent New York.
I was going to just stick this in my linkblog but it facinated me enough to want to make an entire post about it.
Transparent NY is an map with different overlays…historical NY, landfills, elevated trains, rails, farms, office buildings from different periods, all sorts of maps. On the main site is a perspective fly thru, a skyscraper timeline, and an animated Manhattan that you can flip and rotate and all sorts of fun things.
Interactive, interesting. I like it.
