I went and saw the Mannahatta Project at The Museum of the City of New York a while back and it was quite possibly one of the most boring museum exhibits I’ve ever been to. It effectively made me not want to buy the book despite my huge interest in New York City’s history.

What I did not catch at the museum exhibit was this neat Google Maps mashup of the Mannahatta Project and the renders of what Manhattan used to look like. You can literally click on any street in Manhattan and view it’s history and see what it looked like back in 1609.
