# Arc Carousel

> Photos ride the rim of a giant wheel whose hub sits below the frame, like plates on a specimen dial. Drag with inertia, scroll or use the arrow keys to turn it. The centre plate lifts out of the arc, a ring of ticks turns underneath, and the title swaps with a blur-and-tracking morph over a wash of the active photo's colours.

## Install

One-time setup (needs a subscription):

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

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

```bash
npx shadcn@latest add @assembli/arc-carousel
```

Registry item JSON: https://assembli-rho.vercel.app/r/arc-carousel.json (send `Authorization: Bearer <api key>`)
