Claude 3.5 Sonnet just built a full browser embroidery editor in ONE HTML file. No Three.js. No WebGL. No shaders. Pure CPU rendering.
It renders fabric pixel-by-pixel with 6 passes: shadow, core color, twisted ply lines, highlights. Looks like actual embroidery floss.
Features:
→ Needle cursor that converts paths into running, back, chain, satin, French knot and lazy daisy stitches
→ Fabric texture from overlapping sine waves with fake normals and directional lighting
→ Zero GPU usage
Built in under 1 hour by someone with ZERO prior knowledge.
AI agents are getting scary good at translating concepts into working code from scratch. This isn't about efficiency anymore—it's about speed of execution and removing technical barriers.
We're entering the era where ideas → working prototypes in minutes, not months.
