Nice effect.

Actually you can do this in XAML only with Siverlight 3. SL 3 supports Behaviours which can trigger storyboards on many mouse events, including the basic MouseLeftButtonDown.

By putting a second duplicate (and reversed) image on the back of each, with a Behavior to trigger the reversal effect, I was able to reproduce the same effect with no code at all. The only other change I made was the have the storyboard change ZIndex at the halfway point, so that the back image is shown instead of the front enabling the reverse mouse event.

Cheers
