Lightweave is a large-scale, permanent, outdoor, interactive public art piece to be installed beneath a train overpass in Washington, D.C. It is scheduled for completion in late 2018. Lightweave senses the city through motion and vibration sensors, reacting to people and trains passing by with cascades of colored light, while also providing an ambient light source for daily safety and use. The piece consists of six, 65-foot groups of steel suspended below the underpass, each unique in shape and character.
