This is a super lo-fi, Herokuable (Totally a verb, shut up) build server indicator. It doesn't need anything other than a browser.
Clone, then make a copy of public/settings.example.js
and fill you buildbox project name and API key. It will automatically enumerate all your builds in the project.
Put the stuff in public on a webserver, and hit the server. All done.
Otherwise, create a Heroku site and push it. It should just work(tm).
