# Loop

> Taffy pack: a ring of soft-touch apricot dough, thick at the bottom and thin over the top, paling to peach round its hole. Its weight slowly rolls round the ring, so the hole drifts and the loop seems to knead itself. A tap pulls it wide like taffy and lets it snap back with a wobble. Drag to turn and fling it. Raymarched in WebGL.

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/taffy-loop/taffy-loop.tsx` and installs dependencies):
