# Parable of the Polygons

- Author: Vi Hart and Nicky Case
- Source: https://github.com/ncase/polygons (gh-pages branch, the published site)
- Commit: 3ec3fd74a52ce24f74790a47f117d1a3abefbbb7
- Licence: CC0 1.0, public domain dedication (./LICENSE.txt)
- Vendored files: the whole gh-pages branch at that commit
- Added by Web Curio: stage.html — the original page plus a strict Content-Security-Policy (only this site's files may load) and ../_shared/sandbox-shim.js (in-memory storage, Worker and image CORS stand-ins for the sandbox); this file
- Modifications to the original: none. This is the one original the museum runs with allow-same-origin: its page talks to its own nested frames (scroll position, visibility). Its own code (64 KB, read in full) uses no storage and makes no requests.
