  <h2>Letters</h2>
  
  <p>Drawing letters to the screen in Processing
  uses a technology developed in the mid 1990s
  at the Visual Language Workshop at the MIT
  Media Laboratory. It is a closed system,
  but we have supplied a number of fonts
  located in the "font" directory in the main
  "processing" directory. We expect to change
  the Processing font technology in the future.</p>
