I'm really not a fan of the image sequence that loads in the background and the scrolling of the page is hijacked to move between the "animation" scrolling the image sequence. If anything, that should be a left/right scroll when the element is active or at least on element:hover. Stopping the expected page scroll to now start "animating" this media element until the end which then releases the scrolling back into the expected behavior is clearly designed by sociopaths and sadists.
