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