The puzzle pieces in the cutout are like techtonic plates, prone to shifting the image. The paint design stays quietly in place, or trips over the fissures, or gets tweaked over, or merrily trespasses.
But there's more! I've lately become intrigued about fractals, repeat shapes in altered scale. The cutout, zoomed down, informing the shapes in the picture. Like tree and twig.
And the square spiral!
