Remember the [Etch-A-Sketch](http://en.wikipedia.org/wiki/Etch_A_Sketch)?
An Etch A Sketch is a thick, flat gray screen in a plastic frame. There are two knobs on the front of the frame in the lower corners. Twisting the knobs moves a stylus that displaces aluminum powder on the back of the screen, leaving a solid line. The knobs create lineographic images. The left control moves the stylus horizontally, and the right one moves it vertically. – Wikipedia
