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.)
