To hom it may consern, I thought it would be nice, when you write one side barks , it would blink when put it's twin bark. Or when you move the marker (the blinking thing thats "writes" the letters) on a pair of barks, they would blink, so you could know you handnt foget to close the barks of the eqwations.
