Artist and M.I.T. grad Jim Campbell has a new installation—Scattered Light—that was just unveiled at Madison Square Park, and which features many, many light bulbs. One part of the installation is comprised of 2,000 LEDs spanning 80-feet and displaying flickering human silhouettes when seen from a certain vantage point, according to NYCLovesNYC.

The second part of the installation has the LEDs encased in a glass-brick wall; the Madison Square Park website says, “The light pulses emanating from each tablet will be rhythmically modulated to represent the voices of individual travelers as recorded in conversation on a subway platform, combining to create a visual symphony rendered in light.”

Campbell's installation will be on view through mid-February.
