NB: this is a framework for you guys to dump into your existing themes and start making them responsive. It is NOT a theme.
As with all my stuff, it can probably be better, so send me a pull request.
I'm on twitter: @ldn_tech_exec
Features:
- Adds the Skeleton grid as a layout in Magento instead of 1column.phtml or 2column-left.phtml etc
 - You can add no-frame.phtml to any page via layout update
 - …even for CMS pages or category/product layout updates via the admin
 - includes Paul Irish's html IE classes from HTML5 Boilerplate
 - includes facebook compatibility (xml stuff in the html tag)
 - includes tag to make responsive designs work
 
I originally built this for http://www.getbrandid.com and then presented it for http://magento.meetup.com
