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.)
