:) Sorry about the vague "eight-ness" there -- I just mean I see lots of patterns with eight prominent features, or "spokes." I saw quite a few with sixteen spokes, and probably higher powers of two as well, though I wasn't in the mood to count the large numbers. And regarding "prime-ness", I mean I didn't notice any patterns with 7, 11, or 13 features -- that sort of thing. I suppose the prominence of powers of two has something to do with "period doubling" in chaos theory, I don't know.
