¨¨##¨¨¨### 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.)                 #¨#¨¨¨¨¨¨#
