Each cell grows, then splits in two when it gets big enough. Cells repel where they overlap and lightly stick to neighbours, so the cluster relaxes into organic packing. The morphogen is a Gray-Scott field diffusing across the tissue; in fate mode each cell is painted by the local chemical it reads.
