Forgot to mention: this site https://www.metaflop.com/modulator https://www.metaflop.com/modulator ought to be better known, and I ought to remember to mention it every time I mention METAFONT. One great drawback of METAFONT, which held back (still does, but used to too) its adoption in the decades when we could have wonderful things built on it, is the lack of quick visual feedback. (The bigger one of course, is that most font designers don't want to describe their shapes with equations: they think in curves, not about curves.) As I understand it, the site is developed by a couple of enthusiasts and goes a long way to address that problem. At https://www.metaflop.com/modulator https://www.metaflop.com/modulator just adjust sliders to create a unique font (or get something random by clicking "flop it!", and then tweak it). You can even download the resulting font if you like it.
