For anyone curious, Beaker is a browser that can download websites over the Hypercore protocol, which is similar to Bittorrent. Bittorrent is just a way to download files, so why not HTML and images? This is cool because anyone can seed a site to keep it up forever. To fork a site, you just download it and rehost it yourself after making whatever changes you want.

Note that Hypercore is different from Bittorrent in that you can actually update your site after you originally create it, although older versions are always available.
