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.
