Interesting stuff. A rule like: 'fire if my right-hand neighbor is firing'
would generate leftwards trajectories. You could elaborate on that to get
traces to bounce off each other is you added a second class of firing
mode. Are you looking for something deeper than that - what's the target
you're trying to fit? Are you just doing thresholding on local neighbors
or are you using a more sophisticated class of 1D automation?
