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.)
