The Cover of the December issue of marie claire features a very Harry-Potter-esk moving portrait of Emma Watson.
Ceros Hot Studio published this as a digital magazine via zinio, the Magazine is available as a standalone library app in the AppStore.
In fact, they did a very clever job for the rest of the magazine: For the most pages, they ported the normal print spreads onto the iPad (works good in horizontal orientation). Interactive elements lay above the print layout and flash every time you scroll to the page.
On the technical side the cover is just a full-page video with all the typography rendered into. It might be to stressfull for the iPad to mix text and video. And the headlines on the cover are not interactive. It is just a video, but a great idea.
