The Build Guild is a monthly meetup of web folk that revolves around two things: beer and fun. Conversation about the web is optional. In order to portray that lively atmosphere, their website needed the same open, inviting look and feel along with the integration of social networking (ie. Twitter and Flickr).
The little details here are what really seal the deal, from the twitching mustache in the header to the CSS rotation on the photo and on down to the ridiculously awesome footer link that runs the credits as a scrolling movie ending. Superb work overall.
