Vista - Starting animation on MouseEnter

I'd like to start a simple doubleanimation when user moves mouse over a
button, tried all alternatives but can't find any solution.
Does anybody has a simple snippet to share?

Thanks

The snippet below will enlarge the font size, it's very simple but
should get you started:

<Style TargetType="{x:Type Button}">
<Style.Triggers>
<EventTrigger RoutedEvent="Mouse.MouseEnter">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Duration="0:0:2"
Storyboard.TargetProperty="FontSize" To="50" />
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
<EventTrigger RoutedEvent="Mouse.MouseLeave">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Duration="0:0:1"
Storyboard.TargetProperty="FontSize" />
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
</Style.Triggers>
</Style>
