This isn't "replicated computationally" (Score 1)

The blurb from the slashdot submitter makes it sound like they used computers to generate a huge crowd, when in fact it was just the same 3/4 people running up the beach themselves, then walking back, and doing it all over again in a different direction. Lord of the Rings used a computer program to generate the actors which were completely CGI... this was just splicing all the recordings together.. a lot simpler (and in a way nearly as complex).
