I'm really surprised that nobody picked up on the fact that sunflower seeds make neat spirals in the center of the flower. No takers?

If you find good and free vector spirals - I can made variant of "Proposal five" with it.
maybe something like this can work as a basis?
I taked old monochrome version, but (1) haven't manage to pick right colours, and (2) I think that smaller pieces inside with bigger outside fits better, (3) I was moving this inside a center of the flower, but it always seemed that center is not in the right place.
