On closer inspection

A little further down the fish ( which frankly at 6mm long was far too big) the beautiful patterning continues
like sunspots on a strange sun, Painted on such a translucent canvas as to allow us to get a glimpse of the underlying structure. There like the bands of clouds on a fast spinning planet far back in the solar system is the spine. The optical illusion fades and it is no longer a spherical planet but a flat 2D image of a fish bone. For me the mind image formed while undertaking the venture is indelibly printed the breath is still caught away and find myself caught back to reality with a jolt " What are you doing now? Get a  real life"

Beauty like appreciation is obviously  in the eye of  the beholder. No point trying to explain so back to the mundane.
