Windows Phone 7 UI (Metro) possible on iOS?

How hard would be be to recreate Windows Phone 7 UI animations on an iOS device using UIKit? More specifically, making animated boxes gradually move from side-to-side, and appear in a chained manner.

For example, windows phone 7 transitions here: http://www.youtube.com/watch?v=EUeNCzRhhDE

At 0:30 - the parallax scrolling effect (relatively easy?);

At 1:22 - the chained animat开发者_如何学Goion of the home screen;

Is this possible with CoreAnimation and UILayers, if so how complex would it get?

Thanks

It's not incredibly hard. For some things like parallax scrolling you can just use some of the basic view animation code and set different timings for different elements to get the effect.

Look at the animations Apple has in the Apple stores for providing help (similar to some of their screen savers). These are similar to what Windows is doing.

The bigger question would be whether it improves the user experience or just makes them wait longer to be able to interact your application.
