Random initial row

Each cell's next state depends only on itself and its two neighbors, giving 256 possible rules. Rule 30 is chaotic (used as a random generator); Rule 110 is proven Turing-complete; Rule 90 draws a Sierpinski triangle.

Governing equation

s_{i}^{'} = f (s_{i - 1}, s_{i}, s_{i + 1}), rule = 30

Reading this result: Rule 30 is chaotic: from a single seed it never settles into a pattern, which is why its center column is used as a random-number generator.
