Neat interactive One Pager for a jQuery plugin that creates an app like menu system for your website. Love how you can experience the plugin in that phone demo.
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 15 May 2013.
