zurb released a comparable and quite beautiful framework called 'foundation' http://foundation.zurb.com/

Not seen that one before, thanks!

I've also found skeleton: http://www.getskeleton.com/

I discovered ZURB's Foundation 1-2 months ago, and I absolutely fell in love with it. My only problem is I started developing a site with it, and before I knew it they had already shipped out a new version - they are apparently at a stage where their release cycle is pretty quick. I ended up deciding to take a day to convert the project over to the latest version of Foundation, 2.1.3 as of this writing.... here is their github repository: https://github.com/zurb/foundation - I love it.
