Rule 30: one black cell

Rule 30 is a one-dimensional cellular automaton rule, also known as the 'holy grail of cellular automata'. It was discovered by Stephen Wolfram in 1983. The rule is applied to a one-dimensional array of cells, where each cell can be either black or white. The rule is defined by a simple set of rules, where each cell's next state depends on its current state and the states of its two neighboring cells. Rule 30 is notable for producing complex and intricate patterns, and it is considered a fundamental example of a chaotic system.
