Crystallize is a meditative browser app built around the 5 Platonic solids. You start with one solid at the center of a dark space and grow a fractal structure by adding solids one face at a time — each one a geometric reflection of its parent. No account, no server, no tracking. Runs entirely in the browser. Built with p5.js, Tone.js, and significant help from Claude (Anthropic). → crystallize.click
