This is pretty cool: an OpenType parser written in JavaScript, enabling direct manipulation of a font’s letterforms and other typographical controls right in the browser (or node.js). I don’t think it would be used in production, but with type foundries cranking out OpenType variable fonts, it might be a fun playground / experimentation tool.
