    Take a look at this SilverZine tutorial posted by Phil Middlemiss and find out how to animate the Silverlight opacity mask.

    In the context of animation, one of the biggest features in Flash that is missing from Silverlight 3 is an Opacity Mask layer. I haven't seen any mention of this in to Silverlight 4, but I could be mistaken. The only feature that we have in Silverlight 3 is the OpacityMask on each element, which is either a Brush or an image - (Image Brushes don't tile either, but that's a post for another day).

    Phil Middlemiss describes a behavior he has written that allows you to create an Opacity Mask that can be animated.

    Masking with a behavior
    An Opacity Mask "layer" allows for animation, so you can do things like a moving spot light revealing parts of an image, or have a foggy border animating around something.

    This is a Behavior I've written that lets you turn a FrameworkElement into an opacity mask for it's parent container.
