Artist Leo Villareal has completed a light sculpture along the walkway connecting the East and West buildings of the National Gallery of Art in Washington DC. The work, called Multiverse, uses about 41,000 LEDs that run along the 200-foot-long corridor.

The programmable LEDs run through channels along the walls and ceiling that provides a constantly changing background along the walkway. The evenly spaced LEDs provide a visual show that is one part disco and one part "the Matrix." The moving psychedelic patterns along the walls and ceiling of the hallway form dynamic montage of changing shapes from moving single dots to lines to cloud-like shapes, to a spray of mist across a window screen. People crossing between the two buildings can watch the light show as they traverse the hallway on one of the two moving sidewalks. Other pedestrians appear to be moving shadows as you travel down the vast hall.
