This is the interactive version. Almost every page has links you can click to watch videos and read more about a topic.

Slide/page 3 has clickable icons to take you to those pages. I guess thats what they mean by "interactive".

Oh wow, I didn't realize those were links, looks like there are a handful scattered around.

Most of them can't be found unless you hover your cursor over the box, which is less than ideal to say the least.
