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