I only had a minute to look through your code and example...I have to say this is fabulous work! Thanks so much for making this open-source!
What do you think about adding some support for ViewStates? For instance, it would be great if there was some ViewStates for the coverflow items. So maybe when the item is on the side, it's a certain state, and when it is brought to the front,
it changes to another state. This would allow designers, in Blend, to possible make the cover item glow as it comes to the front...or make the other items in the back "dim" until they come to the front.
Thanks again for this gem,
