Empty, but not abandoned, this cavernous Brooklyn loading dock was once considered the largest individual building in the world.

Bill Brand presents an animated movie to passengers on the B and Q subway trains coming into Manhattan from Brooklyn. The project was modeled after the zoetrope, a 19th-century optical toy, which animated images inside a revolving cylinder, so that they appeared to move when viewed through narrow slits. Brand mounted 228 hand-painted panels in self-contained, illuminated units along the three-hundred-foot platform. Hop on a Manhattan-bound B or Q train at the Dekalb Avenue stop (corner of Dekalb Avenue and Flatbush Avenue Extension). Look out any window on the right side of the train.

I have old friends in San Francisco who grudgingly tell me that the High Line is everything that's wrong with New York. Well, too bad. To me, it embodies a culture that's constantly reinventing itself: a defunct elevated railway that was becoming a burden to the city ("we used to climb up there to throw garbage bags full of rotting Korean food at the Hasids!", noted a successful photographer's assistant) becoming a startling example of urban greening for the public good. The expert landscaping makes it feel like walking on a Montauk beach - but a stone's throw from some of New York's most progressive galleries and hotels.

Unlike a lot of neighborhoods the sidewalks in this area are often still paved in the original slate slabs. You can see “extra” pieces sometimes chained up outside like this…. Why pour concrete?

The smell when you step in says it all.
