Hughie,
I'm not sure whether to look from the top down, or the base up.
From the top, all the spirals start (almost) the same width and then scatter and change, new ripples arrive and disappear in a tumultuous sea,
Or looking upwards, that tumultuous sea of different ripples all come together and smooth out to create a harmonious rim.
Works both ways for me, I think one of your more interesting pieces.
