Yet Another Responsive Grid (YARG)
A flexible grid system designed to work with responsive layouts using SASS and media queries.
Based heavily on Jonathan Clem's flexible grids: http://jclem.net/2011/05/16/flexible-and-semantic-grids-with-compass/
YARG is built with SASS, and requires an environment that can compile .scss files on-the-fly (i.e. Rails), or for CSS assets to be precompiled.
My initial blog post on YARG is available here. More in depth documentation and examples are forthcoming!
