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.
