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.)
