I wonder if there's any way to transform this approach taken by Amy Goodchild into actual font files: https://www.amygoodchild.com/blog/cursive-handwriting-in-jav...

It's unfortunately not very easy to generate modern TTF/OTF fonts from Metafont sources. If you're careful to not use any crazy pens, you can compile with Metapost and then import the outlines into FontForge, but it's still fairly tricky to make everything work properly.
