[OTVar] Play with variable fonts in any browser using fontkit

Just wanted to share a quick demo I put together using fontkit, my JavaScript font engine. It lets you play around with variable fonts in any relatively modern browser. It uses the Adobe prototype font by default, but you can also choose your own file. The font is parsed client side by fontkit and glyph rendering is done on a canvas element. Fontkit supports both TrueType variations as well as CFF2.

Demo is here. Code is on Github. Let me know what I can improve!
