This manic-looking machine would allow you to typeset with a variety of styles: "Vari-Typers were not ordinary typewriters but composing machines that made professional looking camera-ready masters for offset (photo-lithographic) duplication."
"This machine could use over 300 different type styles and write in 55 languages; it could adjust the space between characters, and even produce right-justified copy. Even though the Varityper enjoyed a successful career of about 60 years, you may never have seen one, for the machine was not generally adopted as a standard typewriter. Instead, it found a niche as a "cold typesetting" or "office composing" machine: it was generally used to produce neat, camera-ready copy for offset printing, at a cost much lower than that of conventional printer's methods."
