Polyhedral geometries have beguiled scientists, philosophers and mathematicians for centuries. In recent times polyhedral shapes have been identified in closed crystalline membranes such as viral capsids, fullerenes, bacterial organelles and multicomponent ligand assemblies to name a few. The connection between the configuration of these complex systems at the microscopic scale and geometric principles has fostered many scientific discoveries. We describe here the spontaneous emergence of regular and irregular polyhedral geometries in shells formed by more than one component, and demonstrate mechanisms to control their geometry. This work promotes the design of polyhedral micro-containers for various applications in materials and life sciences.
