Joha – a free browser-based drawing playground with preset shape tools

I built Joha, a free browser-based drawing playground built around preset shape tools. You can click or drag to quickly generate individual shapes like waves, stars, layered squares, particles, textured strokes, and ring patterns, then combine them into larger compositions. It’s designed for fast visual exploration and composition rather than precise vector editing. Under the hood, it’s built with Vue 3, Vite, and p5.js for the drawing engine.

In plain words

Joha is a free browser-based drawing tool that emphasizes quick visual exploration over precision. Users click or drag to generate preset shapes including waves, stars, layered squares, particles, textured strokes, and ring patterns, then combine them into larger compositions. Built with Vue 3, Vite, and p5.js, it's designed for artists and designers seeking fast, spontaneous creative play rather than detailed vector editing.

  • 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:…
