From Laura McGough's March 2015 Sculpture Magazine Review:
Timothy Noble’s The Semi-Automatic Chalkboard, a robotically controlled drawing machine, offers a timely consideration of artistic labor. Using open-source software and servo motors to run coded motions, the chalkboard etches out reproductions of sketches created by Charles E. Burchfield in preparation for the oil painting Grain Elevators (1932–38). Working much like an old daisy printer, the automated machine interprets each original drawing by methodically positioning and repositioning itself across the blackboard as it prepares to lay down another stroke.
