If you go to the Herman Miller site you’ll see an interesting way of promoting their “revolutionary” Mirra chair, pegged to be the first great chair after the Aeron (which I’m sitting in as I type).
At the top of the page, you’ll notice a cropped image of the bottom of a Mirra chair. It looks like this:
Clicking on the chair takes you to a rather large but overall effective Flash animation that explains the key features and benefits of the chair. Given that the chair is being sold using design aesthetics and sexiness as key drivers, this seems very effective.
