One of the most interesting UI interface is the Pivot (some call it Panoramic). I look in the tools provide by Microsoft to see if the control was available. But at this time, there was no control available. So I've look on the web and find a lot of interesting stuff on that subject.
I found some blog showing how to create the this kind of interface. Here is some links:
I’m also following Tim Heuer on Twitter(and on his blog) and he post some reference on controls that implement the Pivot. Those controls are very easy to implement, because they implement template so we can implement as many section as we want. So you only have to refer to the DLL and use it as any other controls.
I hope you will find these links interesting.
