Looks lovely! The art of fonts is something I will never understand but always appreciate. This website is also brilliant in showing everything dynamically and explaining why it all matters. Safe to say Github will start using it everywhere? It's also open source, which is nice (and makes sense considering what Github is striving for).

Edit: Not 100% sure on texture healing though. Toggling it on and off in the example makes me feel like texture healing makes everything look weirder. It makes the font look less monospace which should be good, but it just messes with my mind when some letters look slightly different in different contexts. Like the spacing is not immediately obvious to me and having the same letters look different is throwing my mind in a loop. I guess I'll need to try it to see if it's comfortable.
