In the process, I stumbled upon what I think may be a significant milestone in the machine learning and artificial intelligence fields: I have created a behavior model for the most basic of human instincts: panic.
In the first shot, two "pedestrian" particles approach each other, and collide, because they fail to adapt to the situation as time unfolds. In the second shot, they are programmed to "turn right" if they sense an oncoming collision and feel threatened. However, I neglected to provide them a means of relief, and lacking a "fight" instinct, they are doomed to perpetual "flight".
I feel this way quite often on the streets of New York City...
