Side question: Why is nobody making QR codes on web pages clickable (regardless if it’s an image or text-based)? Not every QR code represents a URL, of course, but many do. Maybe there should be a qrcode URL scheme that lets browsers behave the same way as a camera scanning a QR code.
Font shaping rules are actually turing complete. An incredible amount of engineering effort has gone into this not being a total disaster everywhere at all times.

See https://github.com/jimparis/qr-font/blob/master/design.md for the actual design. As who have written a QR code encoder library... I'm in shock and awe.

This is absolute black magic. I never realized OpenType rules were powerful enough to render something as complex as a QR matrix inline.
It’s basically Turing-complete: https://simoncozens.github.io/fonts-and-layout/features.html
Once something is Turing-complete, the magic turns from black to white. ;)

That's a wonderfully cursed idea.
Selecting parts of the code (in F7 mode or with SHIFT-LEFT/RIGHT) highlights which individual pixels corresponds to the actual letters.
That's a wonderfully idea. I Like
Wow. This is so freaking cool.
This is terrifying, great job!
Impressive work!
Not mentioned is the fact that the resulting QR Fonts are huge --- much larger than the javascript needed to render a QR code.
