A careful hybrid of Flash and CSS, this site is dynamic but very usable. We didn’t go overboard with the Flash, but rather used it selectively to highlight important sections and to make a seamless and clear navigation. The layout is clean but the content is actually very deep.
The four main sections, Who, What, How, and New, help organize the content into logical buckets so the visitor can breeze through quickly or dive into more and more content. The case studies also have layer upon layer of text and imagery presented in a way that's not overwhelming. And there's a lot of fun stuff nestled in there, too.
