Gull Call.                            
  
                                          
 The Seagull  Is A  Metaphysics Trick;  A 
 World-Builder'S  Shortcut,  To Define  A 
 Section  Of Reality And Imply  Its Size: 
 Place A Flock Of Birds  At The Edge  And 
 Make  Their  Calls  Tesselate  Over  The 
 Entire Volume                            
                                          
 A Seagull Can Be  Defined By  As  Little 
 As  Five  Vertices;  Six  Triangles.  (I 
 Would  Recommend Handling In  Swarms  Of 
 At Least A Dozen Birds.)
