What do you think about the UI styling?

I love the smoothness and the parallax, but the style seems a little muddled and not elegant. Of course this is just a nitpick. In the end such things matter little to me and functionality wins over my heart -- heh, just like with women.

For the gallery interface: it would be far nicer if the tiles tilted based on the speed of the scroll. Again, a nitpick, nothing serious.

Back to the styling: I think the list items need better spacing, typefaces and placement of in-list icons. Also the transition effects on the rotate and the sideways-pan-to-next-screen could be far nicer. In the end, tiny tweaks by a seasoned graphic designer could make all the difference in the world and truly make this a first class interface.
