        Title="MainWindow"
        Height="450"
        Width="800">
    <Grid>
        <behaviors:Interaction.Behaviors>
            <behaviors:FluidMoveBehavior AppliesTo="Children" />
        </behaviors:Interaction.Behaviors>

        <Rectangle Fill="Blue"
                   Width="100"
                   Height="100">
            <behaviors:Interaction.Triggers>
                <behaviors:EventTrigger EventName="MouseLeftButtonDown">
                    <behaviors:ChangePropertyAction PropertyName="Fill">
                        <behaviors:ChangePropertyAction.Value>
                            <SolidColorBrush Color="Red" />
