It's simply a Flash movie embedded into a web page. Very nice and professionally done but not "accessible" to visually impaired people. Ideally there would be a normal text version of the site to make it fully accessible.
Actually Bluedreamer, depending on what they used to build the movie, they could make that movie accessible. Newer versions of Flash allow you to define elements, that are reported to MSAA, which screen readers can grab.
Even if that were true, what happens to screen reader users on the iPhone or iPad (I actually know quite a few) or those using screen readers on alternative platforms (other than Windows like Linux or Mac) or those with motor function impairments - which that specific animation only complicates. Sorry to say it but static content is the only way to eliminate the major accessibility issue spectrum - even if you can make it screen reader friendly (for a limited crowd). Personally I wouldn't qualify "accessible" as "some screen readers can use it if you make a few changes", it's certainly not in the best interests of all users to follow that model.
