   Emphasis seems to be on the methods for generating the f+c structure,
   i.e., finding landmarks, paths between nodes, what nodes to show, etc.
   Some features use in the example views:

        - nodes are shown as cubes (focus node as a sphere) with titles
        - node size/height/color depicts importance/access frequency
        - landmark nodes distinguished by color

-       - torn shape from a texture, mapped on the paper
-       - stencil buffer for drawing the fragment on the 
-         silhuette
-       - a non-photorealistic black line as the silhuette 
-         edge

+The hardware implementation uses a noise texture for creating 
+the variation in the torn shape with texture coordinates tied 
+to the paper location. 
+The stencil buffer is used for drawing the contents
+inside the buoy silhuette.
+Finally, a non-photorealistic black edge is drawn
+around the silhuette to clarify the image..
