This gentle clack of billiard balls on the green felt behind me makes me think of the endless rolling and occasional collisions of asteroids, spread out along the ecliptic mostly, or rogues in free space tumbling along rebel orbits of their own. We pass unscathed through their geometries. Or do we? Do those bodies too (as the ancients surmised about the canonical planets) cast influences our way, subtle shifts of love and aversion and indifference, so that by them also our moods (those vagrant beasts who live our lives for us) are shaped?
