The Philadelphia trainyard is a stop along the railway between Hampton Roads and New York City. Arriving in the yard one clear April morning, the cobweb of lines overhead dominated the view. The matrix of human infrastructure contrasted sharply against a cloudless sky and presented for the viewer, a unique dilemma.

Is one to focus on the dark lines that do the positive work of carrying energy and information between a who or a what? Or should one focus on the negative space, the seemingly empty, light geometric shapes that represent the relationships formed by the lines? It all depends upon our perception, where we assign value, what we choose to see.
