I developed kate harmer's humcreative.com website recently.
The site is mostly a portfolio site, but it includes lots of small treats, like history pop/pushstate for browsers that support it, and multi-column text, css animations and all those cute buzzwords.
The site also has lots of random backend things built in, like tumblr api-integration for pain-free blogging and html multi-part contactform emails.
The vast majority is structured off a customized fork of the html5 boilerplate + stacey 2.2 that i work on. The site is easy to maintain and was a blast to work on.
