##@@¤%=~~¨ 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 ¨¨~~=%¤@@#
