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.)
