I remember reading about a court case where a man tried to stab a judge with a pencil. There are Google pages full of similar instances around the world. It's obvious that the pencil lends itself to precisely that kind of use. It's not as lacking in dominance as you might think. I have an article on the fallacy of the designer intent because a lot of designers think they can design uses into technology. You can't do that. I use the pen, I make the mark, but the pen is also using me. The pen could be said to be allowing these kinds of marks. I can't do just anything with the pen.
