Trajectories obtained by constraining the activity K, for the three state points identified in Fig. 3. Active sites (n_i = 1) are colored; inactive sites (n_i = 0) are white. (A) For small ϵ, we observe phase separation in time. (B) At a specific value ϵ = ϵ_c, the system is critical, with large self-similar clusters of active sites. (C) For large ϵ, the system exhibits only one phase, and all correlations have finite range.
