A while back I bought my 5 year old nephew a etch a sketch but he never really used it. He told me "it was too hard" to draw. Well a few hours later using some junk pile stepper motors, home made gears and a really simple stepper motor driver, I got it to draw using Turbocnc. There's a short YouTube video here...
