TemplatePlazza have released a new theme which is billed as 'a Yahoo and MSN Alike Joomla theme', but I like to call it a crisp and up to date looking portal.
It has bundles of modules, all collapsible. It has a nice overall look and feel with different width columns as seen on MSN or Yahoo but that allow you to use for different features of content and partner delivery.
Overall, I quite like. The source files come and it does have lots of nice features. I might even be using it myslef ona site.
Anyway, go have a look and play around. It's well worth a look.
