The first LettError project was to make a PostScript font whose lettershapes changed themselves during printing. Traditional typefaces were static copies of physical objects.
Digital fonts are programs and therefore dynamic.
It is not clear whose idea it was in the first place. After simple experiments with a square, we applied the idea to a font. This became Beowolf . Erik Spiekermann proposed Times New Random, but it wasn't Times and Beowolf just sounded gnarly. The story would have existed in many forms until one was written down.
