A simple web page with the same infographics would tell me the same story, take less time to design, print well, work everywhere, and (in my humble opinion) look just as good.
That said, as actual navigation I didn't find the buttons very usable. It would have been nice if there was a visual clue somewhere that the left and right keyboard arrows work.
And good idea about giving some sort of visual cue the keyboard buttons work. I think I might work on something to indicate that. Thanks!
