WPF Recursion Controls

WPF Recursion Controls

WPF Recursion Controls presents a simple language for drawing pictures that illustrates
the power of data abstraction and closure, and also exploits higher-order procedures
in an essential way. The language is designed to make it easy to experiment with
patterns such as the ones in figure , which are composed of repeated elements that
are shifted and scaled. In this language, the data objects being combined are represented
as procedures rather than as list structure.

WPF Recursion Controls is a sample to the power of WPF.
Please take look at this code and try to build your image. ( See samples on the home page)
I would like to get comments.

Beside Sample:

The XAML code:

<E4D:Beside Width="512" Height="256" Content="Beside">
                 <!-- Can be any UIElement-->
    		<Image Source="..\Images\E4D.png" Stretch="Fill"/> 
</E4D:Beside>
 

The Function code:

public static UIElement Below( this UIElement source )
{
            UIElement cloned = source.Clone();
            return Below( source, cloned );
}
public static UIElement Below( this UIElement source, UIElement element )
{
            Grid g = new Grid();
            RowDefinition r1 = new RowDefinition ();
            r1.Height = new GridLength ( 0.5 , GridUnitType.Star );
            RowDefinition r2 = new RowDefinition();
            r2.Height = new GridLength ( 0.5 , GridUnitType.Star );
            g.RowDefinitions.Add( r1 );
            g.RowDefinitions.Add( r2 );
            g.ShowGridLines = ShowGridLines;
            g.Children.Add( source );
            g.Children.Add( element );
            Grid.SetRow( source, 0 );
            Grid.SetRow( element, 1 );
 
            return g;
}

The Result in Blend
