Twenty feet tall light tubes are programmed to respond to the ebb and flow of the tide on the Hudson River. At high tide, the poles are fully lit with a blue light which slides down the pole as the tide ebbs. Cast glass insets of fish swimming are set in the sidewalk. A lace-like fence with cutouts of the local algae and microorganisms lines the pier creating shadows on the pavement on sunny days. This same cutout steel wraps the lower portion of the poles emitting light through the cutouts.
