The full octahedral fractal; one in the center, surrounded by 8, each of those surrounded by 8. Intended to represent the I-Ching, with each of the 64 hexagrams assigned to each of the 64 octahedra. Didn’t seem like it would work out as I’d intended, so it still sits on my workbench. . . awaiting it’s fate. . . I guess I could consult the I-Ching about it. . .
