Prismatic Installation in Washington, DC by Hou de Sousa Glows in the Dark

Hou de Sousa's Prismatic lit up the night in Washington during Georgetown Glow,” an exhibition of outdoor light installations. Led by Nancy Hou and Josh de Sousa, a total of eight designers, engineers, and volunteers assembled Prismatic.

The installation was comprised of 10 cord colors, 55,000 linear feet of cord, and 333 frame facets, and was assembled over four weeks.

To create the site-specific installation for “Georgetown Glow,” Hou de Sousa visualized a cubic volume containing a prism, then frag­mented the shape into nine segments using Rhinoceros software.

The framework con­sisted of 790 pieces of steel rebar.
