A local-first playground for particle life, sand alchemy, orbits, quantum circuits, XR scenes, gesture/gaze tools and kinetic path art — all running in the browser.

No — particle life, sand and kinetic art run entirely in your browser. Satellite TLE fetch is optional and can use pasted TLEs offline. WebLLM and similar heavy assets stay opt-in.

WebGazer is GPLv3 and XR Animator is CC BY-NC-SA — ToolHub skips those embeds and documents a MediaPipe rebuild path instead. Quirk (Apache-2.0) loads in a sandboxed iframe with attribution.
