&&.&&.&&.& ---------------------------------------- .&..&.&.&.
.&..&..&.& .&.&&.&.&.
&&.&&.&&.& 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.) .&..&.&.&.
