These guys designed their site like a billboard in a way. You can see as you enter the site, the first thing that jumps in your eyes is the "billboard", the header. It uses CSS & JavaScript to flip through graphics, efficiently displaying all the aspects of the site in one place.
The next thing down is the sub-header. It displays a static version of the current features. This is a good way to display a featured product or service.
Then you have the rest of the body. I like this concept and think this is an excellent example for a corporate website.
