I'm beginning to think more about notation, similar to what I was doing back in October/November.
This line noise is actually valid syntax. It has a parser and everything, and is a low-level DSL for producing a Gesture Path[0].
While I can display and parse these sorts of symbols, I don't have a great way of inputting them. That, along with notation systems for higher-level DSLs[1][2], comes next...
