From The Verge:
Though best known for his work on the groundbreaking Cosmos: A Personal Voyage television series, Carl Sagan spent much of his career as a professor of astronomy at Cornell University. Now the school is honoring Sagan with a mesmerizing LED art installation created by Leo Villareal. Incorporating over 12,000 individual lights and measuring 45 x 68 feet, the tribute is visible from Cornell's campus and can also be seen by nearby residents in Ithaca, New York. Villareal's installation, appropriately named Cosmos, displays a shifting sequence of dynamic light patterns meant to conjure up thoughts of the stars and sky Sagan loved so well. Those looking to see the installation for themselves can find it on the ceiling of the Sherry and Joel Mallin Sculpture Court at Cornell University.
