Nice I've been looking for something like this for a long time. I'd recommend getting rid of that transparent black bar at the bottom and the buttons could just be arrows < ^ >, and put in the bottom right corner, since you're funnelling the content in the centre. I find the black bar pretty distracting from the content. Also a clearer separation between the articles would be great. Finally if you used page links (#), the browser navigation could support back and forth.
