Two drupal web sites
Moxie did great things with the design side of the projects. Both the designs intentionally use some similar design elements, as they are related organisations.
On the OANZ web site there is a knowledge-base which is implemented using the Google Custom Search service. It's a way to use google to search across a list of web sites, rather than the entire web. OANZ provided about a dozen web sites that they wanted to include in the knowledge-base, initially.
I've built about 7 web sites using drupal now, and am gaining a deep appreciation of it's power, flexibility and ease of use.
