Google Maps new feature, Streetview!
It looks like they’ve hooked up a laptop and gps to a van with a 360° camera and taken photos of the streets every 5m or so.
I remember reading about the technology and they can make 3D scans of the buildings at the same time. Pretty nifty.

I suggest you try clicking on the blue roads and having a look around. The links above go to the road next to the World Trade Centre site.
