Living systems create structures and functions of remarkable complexity by mastering self-assembly in different equilibrium and nonequilibrium states. Three states can be distinguished: equilibrium, nondissipative nonequilibrium (or kinetically trapped), and dissipative (or dynamic) nonequilibrium. On page 253 of this issue, Timonen et al. (1) report on a model system in which all three states are accessible (see the figure) and show how this leads to a range of well-ordered structures.
