UICapsule blocksfor shadcn/ui.

UICapsule is a curated gallery of interactive React components by Kaiyu Hsu, chosen for interactions the web doesn't usually have: hardware gestures, operating-system motion, physical mechanisms and instruments. Entries include a Dynamic Island, an AirDrop-style radar, Circle to Search, a drum picker, a context menu peek, a 3D carousel, an ASCII renderer, a diffusion-style image reveal, Material You theming from a wallpaper, and an isometric voxel landing page. The catalog can be browsed by element (effects, controls, cards and grids, navigation, data, pages) and by style, from minimal and geometric to skeuomorphic, pixel art, cyberpunk and silly.

Every piece runs live on the site and ships as a shadcn registry item with its dependencies listed, so one CLI command adds the source. It's all free and MIT licensed, and an MCP server lets agents search the collection.
