I redesign my Joomla freebies site using Rumi template framework and make a custom of their first Rumi skin to be more like our fave style - minimalist.
Well this Rumi framework and skin is free so you can also play around with it. You can read what is this stuff anyway on their official site. I think you'll gonna love it. And I already have a plan to make one minimalist skin for this framework and of course also for free. So Stay tune.
