In his early work, Bill Thompson was engaged with pure painting and formalist concepts exemplified by artists such as Piet Mondrian. His later works are often three-dimensional wall installations composed of glossy, jewel-colored organic forms created with acrylic urethane on epoxy. Oxbow, Thompsons large-scale commission for MITs Koch Biology Building (Building 68) is constructed from four joined wooden panels. Reddish-brown and blue-gray painted shapes in varying shades create the illusion of a folded standing screen. Thompsons twenty-two preliminary drawings for the Oxbow painting are on view in Building 68s caf.
