spencer finch's thought-provoking new installation on the highline speaks to the tidal nature of the hudson, which means that it flows in both directions. his highly conceptual piece takes one pixel each from hundreds of photos taken of the river from one minute to the next. these pixels inspire the color of glass panes that are installed in the park's indoor area, and their arrangement speaks of the multifaceted nature of the waterway. the installation is a great reason to head over to the highline before the weather gets too intimidating.
