I found it disruptive and inconsistent. First of all, it disables the scrollbar and Page Up/Page Down, so I had to resort to the arrow keys. Sometimes scrolling moves the screen, sometimes it activates an animation. I found myself repeatedly blowing past sections because I was trying to scroll enough to bypass the content currently on the screen.

There wasn't anything about the experience that wouldn't have been as well served by a normal scrolling page with animations activated by a click.
