Multiverse

(vimeo link)

Multiverse, light sculpture created by 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. Commissioned by the Gallery and on view until November 2009, the work features approximately 41,000 computer-programmed LED (light-emitting diode) nodes that run through channels along the entire 200-foot-long space.
