a = baseline state (origin value, initial energy) c = input fluctuation (external force, noise, neighboring state) b = resulting state (field expression/output)

The rule:

b = \pm a \pm c

Map a + c, a – c, –a + c, –a – c across a grid Represent b-values as color intensities or heights Simulate how a localized change in c propagates across the field (waveform-like, possibly interference patterns) Optionally: animate ripple effects using evolving c over time
