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