Mandelbrot Set

Rotate me round my horizontal axis.
I am a crab in a rock pool.
My pincers and my body close and open.

Examine me under a microscope.
Zoom in on my recursion.
See how my dark moon
is permanently stuck
as it dwindles
to the surface of my Pac-man planet,
both of them broodingly black.

Visit my boundaries.
See how the prehensile tails
of a myriad of shimmering seahorses
cling to the side of their valley
as magnification intensifies.

Now my dimensions are cosmic.
Those who view me are disintegrating stars.
My black hole briefly
makes them shine the more
before it sucks them in.
