Three concentric voronoi spheres nested with each other. Each ball is separate from the other layers.

Contains a smaller version of itself hanging freely by a loop. Outer loop has 4mm hole and is 2mm thick, inner loops are ~1.6mm thick, with ~0.7mm...

Contains a miniature copy of itself. This one reminds me somehow of a mother embracing a child, or pregnant, which seems especially appropriate fo...
