Show HN: Squishy 3D helpers powered by Three.js

Plushies is a Three.js toolkit and gallery for adding soft, animated 3D characters to web pages. It turns 17 selectable silhouettes, including hearts, stars, and clouds, into pillow-like figures with fur, fabric choices, faces, and stitched seams. The site presents them as decorative companions and as AI-helper cursors: visitors can choose a character and an app context, let it follow their pointer, or take control while it pauses its task. A playground demonstrates live status and progress controls, along with ways to greet the helper, mark work done, or resume its scripted behavior.

A workbench lets visitors customize a plushie and see its code update as they adjust its shape, fabric, and face; they can copy the code or share a link. The gallery’s examples place characters in mock interfaces for design, document editing, video production, and other work, illustrating how the helpers might fit into familiar web apps. The package is installed with npm, built on Three.js, and released under the MIT license, with documentation and source code linked from the site. The project is aimed at developers who want to add customizable 3D mascots or interactive cursor companions to a website.
