New York is a city of barriers. I moved in on these modernistic spikes that top the entrance gate to this office building’s driveway, and juxtaposed their horizontal sweep with the soaring vertical walls of the building itself. While the gate tells us to keep out, its warm coloration has already been absorbed in the distant buildings. (Note the splash of gold on the wall at left and the golden reflection in the windows.) The upward thrust of each spike is echoed in the windows and vertical trim on the buildings that rise behind them.
