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.)
