A website hero that draws itself in ink. Beside your headline, a hanging scroll of washi paper fills with sumi brush strokes as thousands of particles follow a seeded flow field, swirling into isobars around pressure centres, and every few seconds the next seed draws a new sheet over the last. It's built from one hero.json with your colours, fonts, logo, words, seal and colophon. You get one page, a paste-in embed, a still picture for reduced motion, and a frame-exact video recorded in your own Chrome. The same seed always draws the same scroll.

Lookbook wrote this package: the Motion Heroes kit, the seeded ink flow field and scroll, the still picture and the examples. The effect follows Anthropic's open-source Algorithmic Art skill (anthropics/skills, Apache-2.0); no code from that skill is included. Credits and licences for the open-source software and fonts it uses are in NOTICE.md inside the download.
