Leo Villareal - Multiverse March 3, 2010

'Multiverse,' the largest and most complex light sculpture created by American artist Leo Villareal, may be seen and experienced by visitors as they pass through the Concourse walkway between the East and West Buildings of the National Gallery of Art. The work features approximately 41,000 computer-programmed LED (light-emitting diode) nodes that run through channels along the entire 200-foot-long space.
