Multiverse (2008), a site-specific LED sculpture by Leo Villareal, is on view in the Concourse walkway connecting the East and West Buildings of the National Gallery of Art. The sculpture, which includes approximately 41,000 LED (light-emitting diode) nodes controlled by custom-designed software, is Villareal's largest and most ambitious work to date. Learn more about the artist's programming method as well as his conceptual and technological inspiration in this studio interview. The sculpture was generously funded by Victoria and Roger Sant and Sharon P. and Jay Rockefeller.
