Spontaneous hierarchical organization of silica by means of a command surface is shown on the cover and described on p. 1055 by Marlow and co‐workers. In this approach, the usual co‐existence of energetically similar structures is overcome, permitting selection of one hierarchical silica structure. A patterned substrate is shown to lead to pixel‐like, simultaneous growth of a hierarchal assembly involving four structural levels. The individual pixels belong to a new class of circularly organized solids.
