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.)
