Everyone knows what an Etch A Sketch is but not everyone has experienced a Skedoodle. Made by Hasbro in 1979, it had a cool round screen, compared to the flat Etch A Sketch screen. It also had a joystick which allowed you to draw shapes in a much more intuitive way. Not only that but it also came with some little plastic templates that you put over the joystick and helped as guides to help you draw shapes.
Check out my pics below and also a great 1979 TV commercial that I found online. You can also see more pics in the Skedoodle entry in The Gallery.
