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.)
