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.)
