The theme Responsive 1 is available in version 0.1.1. You can use it in devices with narrow viewport and meanwhile also with wider viewports. You can test it in this installation with an active user account. Therefore you have to select it in your personal settings. Keep in mind that you see the default template when you are not logged in.
It is strongly not recommended to use the theme as default theme in a forum because of it's current incompleteness. Neither the choice of colours is nearly finished nor has the work on the icon theme begun. On a few places I'm still using the old icons on other places I removed them. So this is really inconsistent at the moment.
