Hi Mike,

> When I was an art director, this was how I taught my artists to weight their line-art drawings.

It looks awesome! But unfortunately I think massively difficult to implement.

Not only difficult just to figure out an automated rule for how the thickening should be applied, but also difficult to edit in Illustrator afterwards as well I think, because I don't think there's any way to make a tapering line thickness like that directly on one long center-line curve, I think it has to be done as a closed and filled shape instead.
