&.&.&.&.&. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .&.&.&.&&.
&.&.&.&.&. .&.&.&..&.
&.&.&.&.&. 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.) .&.&.&.&&.
