Galton board (bean machine)

Realizes: Gaussian / binomial distribution

Balls dropped through a triangular array of pegs deflect left or right at each level. The distribution of balls in the output bins converges to a Gaussian as N→∞. Each peg is an independent Bernoulli trial. Speed: minutes to hours (depending on ball count). Capacity: statistical sampling (scales with number of balls).
