¨####¨¨¨¨¨ 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.) ##¨¨¨¨##¨¨
