The plate displays the series of shapes constituting the evolutionary path associated with the simulation of Figure 1A in our report. The initial (target) shape is labelled 0 (44). Continuous transitions occur within the same color, discontinuous transitions are designated by switching color. The first five discontinuous transitions represent a fast period of relaxation from a random shape. Short-lived intermediates during a transition are shown hatched. Events marked in Figure 1A appear as labelled arrows.
