.&..&.&.&. ======================================== .&.&.&.&.&
.&.&&.&.&. .&.&.&.&.&
.&..&.&.&. 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.) .&.&.&.&.&
