The classic scenario in coarsening dynamics concerns a system that in equilibrium exhibits a phase transition from a disordered high-temperature phase to an ordered low-temperature one, e.g., the Ising ferromagnet. After a sudden quench through the transition temperature, when the temperature changes from above to below $T_c$, domains with positive and negative magnetizations grow in time under the influence of the interfacial surface tension, which acts as a driving force for the domain growth. We give a brief introduction on the subject and present some new results obtained in the last years on the geometrical properties of those domains.
