The Alexandria Museum of Art welcomes visitors this fall with an exhibit of work by Stephen Knapp. Individually tailored for each museum installation, Knapp’s light-paintings embody an inherently unique and wholly original form of art that integrates sculptural, structural, and purely visual elements into compositions that transform their environment and envelop the viewer in iridescent radiance. Knapp employs special glass treated with layers of metallic coatings that act as a selective prism to separate focused light into different frequencies of the spectrum. In his studio, he creates the glass to make a palette that he can use to refract and reflect light onto a surface and the surrounding space. AMoA is open Tuesday through Saturday. 933 2nd Street. (318) 443-3458 or themuseum.org.
