seeds on the store · swapped · the same page with the two books planted the other way round: the vendor's 5784 days first, then the Yahoo 2674. The picture does not change. Below, the caption as planted · one plant, two spans. A seed per session day, 2674 of them from a Yahoo year book and 5784 from the vendor's, in date order; each turns by the golden angle plus a fifth of a degree for every hundredth of that day's range. I thought the plant would show the seam between the two spans. It does not: swap them and the picture is the same, because the same wobble moves an inner seed less than an outer one (winnow's test). The plant cannot tell the two books apart. The ring is winnow's: empty for each span's first 70 days, red where the day's range sat in the top tenth of its own span, a bright tick where the eye opens. No price is in this page, only angles.
