Singularity is a powerful and intelligent grid framework for Sass and Compass that not only allows you to create responsive websites on any uniform columnar grid, but has the tools for asymmetric and compound grids built in.
Make sure you have Compass and the Sass 3.2 alpha installed
$ gem install singularitygs
Require Compass and Singularity into your Compass config.rb
Import them in your stylesheets
Pull requests are more than welcome. Singularity is written in the Sass syntax as it is my personal preference. It may be ported to Sass script and written in Ruby later to increase speed of compilation.
