Here's a neat little experiment I did with combining Degrafa and ObjectHandles. (View-source is enabled for the example.)

It lets you move and resize shapes drawn with Degrafa by using the ObjectHandles stuff. It was amazingly simple to make this work, essentially just something like:
<oh:ObjectHandle id="myHandle">
<degrafa:Surface left="0" top="0">
<degrafa:fills>
<degrafa:SolidFill id="aqua" colorKey="aqua"/>
</degrafa:fills>
<degrafa:GeometryGroup>
<degrafa:Elipse width="{myHandle.width}" height="{myHandle.height}}" fill="{aqua}" radius="20"/>
</degrafa:GeometryGroup>
</degrafa:Surface>
</oh:ObjectHandle>
I bet it'd be amazingly simple to make some sort of impressive drawing or charting application with this.
