I’m calling it “abstract constructionism” because that’s exactly what it is — even though the term doesn’t show up when I Google it.
Depending on point of view and direction and intensity of light source (direct sunlight thru a window being my favorite), these tiny constructions take on an ever-changing appearance, a mesmerizing contrast of brilliant and muted colors, of sharp edges and soft shapes.
Infinite composition, groupings, and optical illusions are conducive to daydream, meditation, and creative thought.
