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.)
