I’m working on projects for rendering code more legibly without editing it.
One project is a proportional coding font, Camelana, which has left-padded uppercase letters when they are part of a camel case identifier.
Also, it has custom ligatures. e.g. the keywords ‘return and ‘throw look like a sticker with a solid background, so it is easy to spot exit points.

Another project is TabularEye, which renders some code blocks in columns without editing the whitespace.

And other little projects like that
