You might want to try out drawing with this multi color pencil made by Japan Camal CA-7C. I bought mine yesterday at Artist & Craftsman Supply in San Diego This pencil caught my eye and said, "Please take me home." The pencil line surprizes you as you draw with it. You are never quite sure what color your line will morph into. This color changing keeps you alert. You definitely won't fall asleep while operating this pencil.
