This document discusses font creation and Prototypo, an open-source web app for streamlining font design. It presents information on building typefaces using systems and coding recurrences, and describes Prototypo's use of outlines, skeletons, and small extendable APIs to manipulate font components through operations like rotation, expansion and distribution. Prototypo aims to make font design more accessible and its developers discuss potential future additions like alternate glyphs and individualization tools.
