Moon Type

I recently learned of the existence of Moon type, a writing system for the blind that uses embossed symbols. For people who lose their sight after learning to read the Roman alphabet, and who therefore already have a relationship with typography, Moon type is apparently much easier to understand than Braille. However, since it's significantly faster and easier to produce a work in Braille, Moon writing has diminished in popularity and is now only used by about 400 people (most of whom live in England).
