Changing the patterning dynamics by varying the strength of k1. The behavior of the Sevilletor model can be easily modulated to transition between patterning regimes over time by varying the parameter k1 in all cells. In this example, the model transitions from lateral inhibition pattern, to rotating waves, to periodic waves with spiral centers, to a bi-stable frozen spiral pattern, and back to a lateral inhibition pattern: k1 = 0.0 → 1.0 → 2.3 → 4.0 → 0.0.
