Three highly nontrivial examples of stochastic resonance (SR) in extended systems are discussed, showing both the degree of maturity achieved by the field and the wealth of potential realizations of SR in extended systems: 1) a bound KPZ system, for which the knowledge of its nonequilibrium potential (NEP) makes simple the solution of very complex problems;2) the Ising-Bloch front bifurcation in an activator-inhibitor system, a case of SR between moving fronts of opposite chirality; 3) a spatiotemporally chaotic toy model, useful for climate research, exhibiting internal SR due to chaos suppression.
