I'm on Chrome on Mac and it's not entirely obvious how to navigate these slides. Going to the link only shows me the first 3 slides by scrolling right. Playing around a bit, I discovered that the arrow keys bring you to the next slides. Perhaps there could be a way to make that more obvious, or provide buttons onscreen.
