There's an "iframe ready" gist now (demo), and it's really easy to theme (I think).
tl;dr you just put this in an iframe and use your path as the URL hash (#IndieAuth, #2014/Online, etc.)
If you're game (just nod), I can fork an alternative theme (maybe without bootstrap) and we can have a theme selection dropdown and a "fork and propose your own theme" link. Could be fun.
