I can remember when a jammed typewriter carriage meant a mess on your paper because of all the letters typed on top of one another. Which goes to show you how I lacked imagination, because artist Pablo Gamboa Santos used those same overlapping letters to create pictures, which he calls "The Qwerty Project.". The one above is a detail from DaVinci's The Creation of Adam, and the one below is the upper part of the Statue of Liberty. It would probably not be Charlton Heston's favorite.
