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