Interesting concept, but it seems to slow at this point. My iPad lagged for several seconds (unable to interactive with the page at all) after the page had seemingly mostly loaded (but before the big background image appeared). Making a lot of requests at load time makes the page unresponsive, especially if you're not even making the requests asynchronously[1].
