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.)
