# Chrome Arrow

> Objet pack asset: a polished chrome arrow, a rounded shaft with a conical head, raymarched in WebGL against studio softboxes. It turns on its own axis so reflections slide along the metal, and every couple of seconds it pokes forward and recoils on a damped spring, like a cursor tapping. Leans toward the cursor, spins when dragged. Zero dependencies.

## 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/objet-arrow/objet-arrow.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/objet-arrow
```

Registry item JSON: https://www.assembli.design/r/objet-arrow.json (send `Authorization: Bearer <api key>`)
