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.)
