This Drupal 6 site has a little bit of almost everything. The design is by Marc De'ath of the Creative Coop, and features attractive but simple graphics and font rendering using Cufon. The main front page image is rotated using jQuery, while the main navigation menu uses plain old CSS. There's a staff blog, events calendar, media materials area, and brochure pages with images and text.
The two most complex areas of the site, however, are the Organic Certification process and the Carbon Calculator. These required the development of a custom Drupal module to contain the reference data and process the results, and a tabbed front-end using jQuery to make the calculator and certification forms manageable for users. There's no space here to go into too much technical detail (send me a message if you're interested!) but at the time of writing this is a unique resource for organic growers in the UK.
UPDATE: A slightly reduced version was moved to a different domain. The description above still generally applies, and I have updated the URL.
