A perfectly round bubble, suspended, jewel-like in a pale turquoise field, is ringed by a collection of other spheres. Are they encroaching, threatening to swallow it up, or protecting it from some unseen threat? The image evokes soap bubbles, or an exquisite adornment of beaded agates or gold-rimmed precious gems. It’s fun to contemplate its meaning, but equally satisfying to immerse yourself in the lusciousness of color and the perfection of shapes.
