¨¨¨¨##¨¨## 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 ##¨##¨####

##¨#¨¨¨¨#¨ a  seagull can  be defined by  as little #¨###¨###¨
#¨###¨¨¨## as  five  vertices;  six  triangles.  (i ¨##¨¨##¨¨#
¨##¨¨#¨¨#¨ would  recommend  handling in  swarms of ##¨#¨#¨#¨#
