The inspiration behind it is the iPad app "Flipboard", with animated page turning. Heres the video:
The effect was created as below:
Flipable element which is clipped with parent Item element so that only the half of the flipable is visible at all times. The flipable element contains a duplicate page content as the underlying element which is just created with HTML formatted Text element. I also added a flavor of shadow to the Transition animation so that inner part of the fold seems a bit darker. Shadow was created with transparent gradient image.
