Simon built a simple cellular automaton (rule 22) model for fracture. He read about this model a couple nights before in Stephen Wolfram’s “A New Kind of Science” and recreated it from memory.
Stephen Wolfram: “Even though no randomness is inserted from outside, the paths of the cracks that emerge from this model appear to a large extent random. There is some evidence from physical experiments that dislocations around cracks can form patterns that look similar to the grey and white backgrounds above” (p.375).
