# Congruent Triangles

Bruce and Katharine Cornwell are primarily known for a series of remarkable animated films on the subject of geometry. Created on the Tektronics 4051 Graphics Terminal, they are brilliant short films, tracing Klee-like geometric shapes to intriguing music, including the memorable 'Bach meets Third Steam Jazz' musical score in ‘Congruent Triangles.’ In this melding of art and science, the Cornwells create a quasi-hypnotic take on a mathematical construct.
