If it's an ruby hash, that's unintentional. I changed one of the I18n paths in the app at 5am (the competition finished at 8am for us) and changed it in most places around the site. I missed the home page (since it uses image replacement) but in some configurations (e.g. I think Retina MBPs in Chrome) it shows up still.

We can't modify code until post-judging, so it has to wait until then to be fixed. And thanks, the cover animation was the work of our wonderful designer, @levibuzolic on twitter.
