##@#%^^-^¨ 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.) ¨¨¨¨¨-^^#@
