 Fillets
 '''''''
 
-Foo
+Filleting, or rounding corners of surfaces, is 
+used in mechanical engineering to improve 
+the properties of cast objects. 
+Our use of the filleting for connections in graph-like diagrams
+is motivated by the Gestalt principle of good
+continuation. Smoothly changing contours enable more efficient perceptual
+grouping of visual elements, in this case,
+grouping of the node and the connection.
 
-Goals???
+In situations where the graph layout is constrained,
+e.g.~Focus+Context views or views where the coordinates of the nodes
+are informative, fillets can clarify the relationships considerably without
+altering the layout.
 
+Our earlier reseach has shown that filleting significantly
+improves the perceivability of certain graph layouts. 
+We plan to obtain experimental justification and 
+to formulate principles of filleting 
+in more general layouts including curved connections 
+and smooth animation. 
+Generalizing filleting to three dimensions ...
