#¨¨#¨¨¨¨¨# 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.) ¨¨¨¨#####¨
