##¶#&*^~~¨ 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.) ¨¨¨¨~^*&#¶
