Mary Corse used glass microspheres painted in acrylic for her artwork which is currently displayed at 601 South Figueroa. Since the early 1960s, Mary Corse has created abstract, monochromatic paintings. The tiny, perfect spheres of glass refract light and make for a luminous surface that is not attainable using pigment alone.

"L.A. Prime Matter" consists of two 32' high triangular bronze towers at the northwest corner of Wilshire and Figueroa. Specially designed ridges in the sides of the towers form patterns in the water that slowly flows down from the top. In contrast to other works in the "Prime Matter" series, in which the flame begins at the bottom and moves up, the fire in "L.A. Prime Matter" spilled down from the top. Though this work was conceived as juxtaposing light, fire and water, only water remains because two components no longer function.
