Great touch here… The background and the shot in the camera are the same: pacifichelm.com/cameranoir (via @uptonic)

I like the idea of this page design, use elements of the photos from the iPhone display of the app in the rest of the design. Like Jason is pointing out for the background image. I like the “slide to download” call to action, it brings interest to what would otherwise just be a static button. While the page isn’t responsive per-se, there does seem to be a mobile layout when you hit the page on your iPhone, in that case the call to action is a neat little experience as well.
