I tried the OCaml version which was much much faster than JS. Had to run around 100,000+ simulations to get 3.14xxx consistently. This is a really simple algorithm so I'd suggest giving it a shot in a your favorite language to see how fast it converges.

It would be interesting to see how quickly a quasi-random, low-discrepancy sequence converges to PI (e.g. a Sobol Sequence).
