&.&..&.&.. 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.) .&&.&.&.&.
