Matita is a set of pencil-style SVG icons, drawn by code from simple shapes (lines, circles, arcs), so every build draws exactly the same paths. 0.4.0 came out yesterday:

• 60 new icons (200 to 260), including a medical and science set, which people asked for last time
• a wobble setting from 0 to 1: <SketchIcon name="calendar" wobble={0} /> draws exact shapes, 1 is the default sketchy look, 0.4 is a calm hand
• ready-made exact SVG files at @matita/icons/exact/<name>.svg
• React, plain SVG, a script tag, a sprite; MIT; no signup

Try the slider and copy snippets here: https://matita.dev (changelog: https://matita.dev/changelog/, what is next: https://matita.dev/roadmap/). If an icon you need is missing, open an issue and I'll draw it: https://github.com/matita-dev/icons/issues

Feedback on anything that looks wrong is very welcome.
