JavaFX morph example code

Here is a quick JavaFX program? script? that demonstrates the morph animation ability in the latest version of JavaFX (I snagged a version from June 1st). In any case here is the code:

/*
* This file is created with Netbeans 6 Plug-In for JavaFX
*/
import javafx.ui.*;
import javafx.ui.canvas.*;
import javafx.ui.filter.*;

var win = Frame {
width: 600
height: 400
content: Canvas {
   content:
       Morph {

           morph: bind [0,.01..1] dur 2500

           fill: blue

           start: Rect {
               x: 10
               y: 10
               width: 460
               height: 140
           }

           end: Circle {cx: 200, cy: 200, radius: 100}
       }

}
visible: true
};

This code should draw a blue-filled rectangle and then morph it into a blue circle taking 2.5 seconds to do it. Pretty simple and slick, although a rather trivial effect.
