 * A spiral: growth over time, a sequence with no natural end, a cycle.
 *
 * Two and a half turns of an Archimedean spiral, sampled every twelve degrees. The
 * longest centreline in the collection and the one that shows what the region is
 * really doing: the dots follow the arm outwards at an even density the whole way,
 * because the packer is filling area rather than stepping along the line.
