Figures & data
Figure 1 Simple models create complex patterns of triangles. (A) Sierpinski triangles: generated by simply drawing an upside down triangle inside the original triangle, then drawing a new triangle in each of the triangles this generates, as indicated in the inset. (B) A cellular automata model, specified by “Rule 90”, illustrated at left. This produces a pattern much like that in (A) if started from a single point. With random initial conditions it generates patterns like those seen here. (C) Neural model of Cymbolia innexa (Boettiger et al. 2009). (D) Photo of Cymbolia innexa.
