# Ribbon

> Flux pack: a wide band of liquid satin looped into a ring with three half twists, so its face and back keep trading places as the twists travel round the loop, while the loop itself rolls like a wave and the band swells and thins. The colored light pours along it as it turns. A tap whips the twists once round the loop. Raymarched in WebGL.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/flux-ribbon/flux-ribbon.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/flux-ribbon
```
