After choosing “Rain” earlier this year as the first installation to transform a series of underpasses, the NoMa Parks Foundation has picked its second piece.

A wave-like structure, ‘Lightweave,’ will be installed from the ceiling, appearing to float above passersby as it illuminates the space with varying intensities of light. It will also be visible from L Street outside of the underpass beckoning “visitors to explore and linger in the beautifully transformed space,” the foundation said. From the release:

‘Lightweave’ will translate ambient sounds from passing trains and other sounds of the neighborhood into dynamic auroras of patterned light. ‘Lightweave’ will animate the underpass with variable intensities of illumination while creating a meditative and interactive experience. Similar to dropping a single pebble into an undisturbed pond, waves of light will slowly oscillate through the space. Multiple sounds will create dynamic visual overlaps. The quality and placement of lighting elements will dramatically improve the experience of the underpass for pedestrians and bicyclists, but will not interfere with or distract vehicular traffic.

San Francisco-based Future Cities Lab designed the installation and submitted it to a competition organized last year by the foundation. Four winning designs (two of which have now been chosen) will be installed in the four underpasses that connect the east and west sides of NoMa.

A community meeting to discuss ‘Lightweave’ is scheduled for July 13, and construction is slated to start in late 2015. “Rain” will be installed this summer.
