This is my first real self-directed creation in Blender/Sverchok following Maks Surguy's great tutorials on using it to create SVG. It is 150 or so concentric circles distorted with Numpy Perlin noise. I love the undulation that gives it an almost spherical form. I plotted it on 11x15 fine art paper with a 0,6 Isograph pen, and it came out great.
