One thing that came out of my research for Beyond Bézier is the Stroke Scribbler, a @RoboFont extension that creates a Noordzij-style cross-hatch to de-emphasize shapes’ outlines. It’s been programmed by (the best and coolest) @arthurfontzarelli and I’m super happy about that. It is available on Github: https://github.com/ECAL-Beyond-Bezier/StrokeScribbler-roboFontExt
