Quiz done specificaly for event HOK2012. It is and Web app (http://www.apple.com/webapps/whatarewebapps.html) for iPad.
Is’t well ajax and uses local storage cache. The designs were provided by a designer, markup and Django backend was done by me.
You can check it out on hok2012.tocka.tk, preferably on iPad, but it will work just fine in modern browsers and iPhone though some scrolling might be required.
