Remember the Etch A Sketch? That shiny red toy that allowed one to create line art as intricate as one's patience would allow and then clear the slate with a shake? While I can't remember picking one up in many years, I do recall being engrossed by the one my grandparents had when I was a child. Try as I might, I could never quite translate what was in my head onto the screen via those two knobs and that unforgiving line.
