The Man in the Spoon

There was a reflection in Metal, which meant
Half-haloes of light-sourced utensil gave flash
Engrossing attention through elegant sense

Maintaining the contra to All flash is CRASS
And lifting the energy drabness let drop
New angles enable new viewpoint: hey presto

If grabbing the O makes a  Cap of a Capo
Now what might become of a Halo? Some question
