Veerle Pieters and Geert Leyseele, very talented designers from Belgium, have just launched their new site:
www.duoh.com
(not in Joomla, but in ExpressionEngine and nevertheless beautiful !)
I've noticed that web designers are like fashion designers...no one is going to wear the stuff that is presented (strutted across) the catwalk, but they will higher them or buy their fashion line.
