The youtube video[0] gives a WAY better introduction to GURT than the website does:

  "This is Gurted — an alternative to the World Wide Web with a custom protocol called GURT
  with enforced encryption, a new DNS with weird domains,
  web browser built in a game engine that doesn’t rely on Chromium,
  capable of running a Minecraft clone, Tetris,  complex UIs, all powered by HTML, CSS, and...
  Lua."
