-%Pyramidal parametrics, Lance Williams (mipmap) ref.
+- natural visualisation of a piece of a large paper\\
+- in a computer user interface a piece of paper can be torn without destroying 
the original\\
+- moving the tear-away area cannot be done with real paper\\
+- the movement should be visualized in a comprehensible way\\
+- the torn shape of a point on an edge should be a continuous function of the 
point's location on the paper\\
+- the function should change slowly enough so that the dot product of movement 
direction and edge normal
+  is visible as the ``rippling speed''
