 Creative Time, Friends of the High Line, and the New York City Department of Parks and Recreation commissioned "The River That Flows Both Ways" to Spencer Finch as the inaugural art installation for the High Line Park.The work is integrated into the window bays of the former Nabisco Factory loading dock, as a series of 700 purple and grey colored glass panes.Each color is exactly calibrated to match the center pixel of 700 digital pictures, one taken every minute, of the Hudson River, therefore presenting an extended portrait of the river that gives the work its name.
