Diagram containing a set of four 3D graphs on the left and one 3D heatmap graph on the right. Each of the four graphs in the set shows four rod-like blobs, or fins, protruding into a space. In the graph at top left, the fins are close together. In the graph at top right, they're placed further apart. Over time, these finned structures evolve into the graphs at bottom left (in which the blobs now overlap) and bottom right (in which the blobs nearly touch but do not overlap). In the heatmap graph, arrows within the coloured area show the direction of convective currents that form around the fins.
