Apparently the Aussies think orangestar.com is awe-inspiring! Check it out in this PB Web Development Blog post featuring inspiring Joomla sites that don't look like regular Joomla sites (from Sep, 14, 2009.)

At Orange Star, Joomla is our preferred Content Management System (CMS).  We partner with The Dev Department for the majority of our development work — and together, we build Joomla sites the right way and, with most of our work, one could never even tell it is using a CMS. 

What is Joomla? Joomla! is an open source, nop-notch. PHP-based Content Management System and it is free. Joomla! is comparable to other CMS's, some of which can cost thousands of dollars. It allows us to build custom designed websites with a user-friendly and standardized administrative interface enabling rapid and cost-effective production of sites that would otherwise be cost prohibitive for small businesses.

• Joomla is open source and has huge market share, so there are lots of resources and support
• There are tons of 3rd party extensions that can be leveraged to save time and money
• Joomla! makes it quite easy for clients keep a site updated as well as add new content quickly.
• It is SEO friendly, so it is great for Search Marketing
