Page flip effect for a Metro Style application

Question

Hi everyone, 

I'm working in a Metro app prototype to simulate a realistic page flip effect when navigating between pages, pls 

see the aka flip page effect demonstration on: http://www.html5rocks.com/static/demos/20things_pageflip/example/index.html   

My idea is to use Frame control navigation to navigate between pages and then implement a custom theme transiction and 

use into a Frame control to apply the page flip effect when navigation from one page to another.

Basically I'm thinking to create a class that inherits  from Windows.UI.Xaml.Media.Animation.Transition  base class, implement the 

custom behavior and them use the custom theme inside the Frame control on this way:

       ....

        <Frame x:Name="mainFrame">
            <TransitionCollection>
                <FlipPageThemeTransition ...>
                   ...  
                </FlipPageThemeTransition>
            </TransitionCollection>
        </Frame>

       ...

I'd like to know your suggestions before I starting to burn me out on this approach, or if you have a better/suitable

way to implement this funcionality.

Regards,

Flavio
