Beauty in Design have been released but neither were initially designed for Joomla but now they are available.
Curiously Green is clean and fast and has a simplistic beauty to it. It was created as an Open Source template by NodeThirtyThree and is now available to the Joomla community. You can download the template here.
The next template is from Swedish designer Andreas Viklund, famed for his Wordpress themes. This time it is a port of his '02' theme. It can be downloaded here.
Did I mention, these Joomla themes are both free! Good work BiD!
