San Francisco artist Bob Van Breda is known for his linear works using only pencils to create gravity-defying sculptures. Adopting the theoretical moment of inertia as his point of departure, Van Breda considers motion, direction and volume as he crafts his sculptures, with no limitations on the length or colour of the pencils used.
