A Mostachioed man with dark hair and a pencil, or several. This is the TV personality I knew in my youth as Commander Mark on the PBS show “The Secret City.” On this show he would demonstrate a method of “Drawing in 3D” and with the help of other performers and guests he would teach an appreciation and understanding of art. His show included many segments on specific art techniques, such as computer art, stop motion and drawn animation and sculpting with plastic. Today he has a new show, “Imagination Station” where he continues his art education for children. You can also find his books on sale in art stores throughout the world.
