# Hot-air balloon

> Jaunt pack asset: a hot-air balloon. Every five seconds the burner roars: the flame leaps, the envelope swells and the balloon rises, then sinks slowly back as the air cools. Pillowed panels in two colors, a wicker basket and sandbags. Raymarched in WebGL with a real ground shadow. Six palettes or your own colors; any number share one WebGL context.

## 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/jaunt-balloon/jaunt-balloon.tsx` and installs dependencies):
