# Glass Lens

> A draggable liquid-glass lens that really bends what is behind it: a canvas-generated displacement map feeds an SVG backdrop-filter, with a specular rim and arrow-key nudging. Falls back to frosted blur outside Chromium.

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/glass-lens/glass-lens.tsx` and installs dependencies):
