Animated gifs of the time evolution of a model plaque.

Uniform model with aggregation, disaggregation and feedback rules. The starting conditions for the system is a solid sphere of 5 pixels in radius. Initially, the disaggregation probability is equal to 0, and as the cluster grows, the feedback increases that probability from 0 to the value of the growing probability. At this point, the number of pixels in the system is stabilized, although the effective radius of the cluster grows in time.
