Slightly off topic, but they way they changed the info graphic as you scrolled was _really_ cool! This is one of the rare cases where extra JavaScript makes sense - it really improves the experience.
By "cool" do you mean it helped you read the article? I'm curious because I had the exact opposite response, I actually quit reading the article at that point. I think it might work better on a small screen, but I was reading it on a full size monitor with the window maximized. It actually took more time to scroll to the next sentence than it took to read the sentence. I found it too annoying to concentrate on the content.
