Animated background control in WPF?

Question

In my WPF application, I want to have an ambient animated background similar to Media Center's background. Is there a free control that offers this?

Answer 1

A way to animate the background is:

It is also possible to set the TargetProperty to "(Background).(SolidColorBrush.Color)" as in this example:

<ColorAnimation
    Storyboard.TargetName = "lblSubGroup" 
    Storyboard.TargetProperty = "(Background).(SolidColorBrush.Color)"
    From = "White"
    To = "Navy"
    Duration = "0:0:3"
    AutoReverse = "True"/>
