One of the things I love about NYC history is the layering and the continuity. It's how I think software should evolve too. We rip up our software cities too easily, because we don't like the arrangement of the streets, forgetting that there are real people living and working in our cities.
So I totally got off on the elevator movie that takes you to the 102nd floor observation deck in the new WTC tower. It shows you how the city evolved from nothing to a small Dutch settlement at the tip of Manhattan (south of the WTC site) to the huge metropolis it is today. You even get a look, briefly, at the ill-fated tower that came down on 9/11.
But there are mistakes, as has been observed, and one howler that as far as I know has not been reported yet. Here's the problem. They show the Brooklyn Bridge, clearly, in 1825. But it wasn't finished until 1883.
