Sounds like a robot defending itself.
Ponca City, We Love You writes "Kevin Kelly has an interesting blog post on how a World War II D-Day invasion was staged in a few days with four guys and a video camera using batches of smaller crowds replicated computationally to produce very convincing non-repeating huge crowds. Filmmakers first used computer generated crowds about ten years ago ago and the technique became well known in the Lord of the Rings trilogy but now crowds can be generated from no crowds at all — just a couple of people. "What's new is that the new camera/apps are steadily becoming like a word processor — both pros and amateurs use the same one," says Kelly. "The same gear needed to make a good film is today generally available to amateurs — which was not so even a decade ago. Film making gear is approaching a convergence between professional and amateur, so that what counts in artistry and inventiveness.""
