Figure 11.2. An example of a cellular automaton. The evolution of the first few
hundred steps of ''Rule 30,'' which states that, if both a cell and its right neighbor
were white in the step before, the new colour of the cell should take the previous
colour of its left neighbor; if not, the new colour should be its opposite. The left and
right lower parts have been truncated. Note some regularities on the left, but
randomness (or pseudo-randomness) in most parts of the system. Various statistical
and mathematical tests failed to find any regularities in the arrangement of the first
million steps below the initial black cell. Based on and modified fromWolfram (2002).
