Other “cell structures” can be drawn. In addition to working out what parts of the animation to draw, the cells must also decide on what time to draw from the animation.

Like clocks on the wall, or firefl ies at night, these coupled cells entrain to each other and a single clock emerges — that of the disembodied toddler. On the way ambiguous domains and subdivisions of the beat may become local attractors for the colony. These will fade over time.
