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.)
