What does the name mean?
A glyph is a particular shape, typically a letter, digit, or other symbol. A font is a collection of glyphs. For example, the Helvetica-Bold and Times-Roman fonts each have their own glyph for the lowercase letter 'a'.
Combined, glyph and cog symbolize machinery (software) for working with electronic documents, which is Glyph & Cog's primary mission.
