RoughNotation – create and animate hand-drawn annotations on a web page
In plain words
RoughNotation is a library that lets developers add hand-drawn style annotations and animations to web pages. It creates sketchy, informal visual elements that highlight or mark up content with a rough, sketch-like appearance. The tool is designed for web developers and designers who want to add interactive, annotated elements to their websites. It stands out by providing an easy way to implement casual, hand-drawn visual effects without requiring complex custom code.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
