Machinery with its intricate parts has a particular kind of beauty. Wheels and pulleys and levers work in unison and, simply put, do things. These particular units stood on Central Park West, in preparation for a movie shoot this coming weekend. I photographed them in infrared and was pleased to see how they radiated sharp detail. Another subject area to investigate. How in fact they will be used, and what in fact they do...beats me. I do know there is a message on the unit that reads, "Not for movement of humans." Go figure.
