Analysis of A Bowl of Glass

Imagine,
picture, if you will,
a glass bowl,
clear crystal --
a bubble.
Create, therein,
an atmosphere,
diaphanous,
of water.
Pebble its bottom
with small shards:
amber, flint,
obsidian and cloudy quartz.
Introduce a coral branch
and set a sprig,
dark green,
of kelpy moss.
Disperse -- suspend --
a fishy population.
Put in motion
this tableau:
habitants in bowl-bounded ocean --
flashing mauve, bright blues,
pink, red, emerald and silver hues,
and yellow.
Regard.
And stow immobile bones
bleached shiny white
below.
