One evening I was walking along Hollywood Boulevard, nothing much to do. I stopped and looked in the window of a stationary shop. A mechanized pen was suspended in space in such a way that, as a mechanized roll of paper passed by it, the pen went through the motions of the same penmanship exercises I had learned as a child in the third grade. Centrally placed in the window was an advertisement explaining the mechanical reasons for the perfection of the operation of the suspended mechanical pen. I was fascinated, for everything was going wrong. Then pen was tearing the paper to shreds and splattering in all over the window and on the advertisement, which, nevertheless, remained legible.
