Another one by the same guy. The one looks neat if you click into the picture and view it on the largest size (4056x3040).
Harvard Medical School Longwood Medical Area by Isaac Kohane, on Flickr

There's something fascinating to me about the Longwood area. It is its own little hive of activity and urbanity somewhat removed from the rest of the city. It's very cool, and yet, you never really want to have a reason to go there.
Yeah - and between the share district utilities, gerbil tubes, underground connections, layered addition & renovations etc. it's approaching beehive / macro-structure status...
