The intrinsic\, natural curvature of shells is the central element that allows for this rich and very interesting morphological landscape\, but it is also the source of geometric nonlinearities that renders an analytic treatment of non‐Euclidean shells\, even under small load\, very difficult. In this talk we examine some snapshots of this morphological landscape. Inspired by the natural folding and unfolding of polled grains\, we use theory\, simulations and experiments to explore the large scale deformation of a confined thin spherical shell with an opening. We then proceed to investigate the surface topography of shallow doubly curved shells resting on a fluid substrate. The frustration due to the competing geometry of the flat substrate and the curved shell produces a wealth of highly reproducible and ordered\, or random and disordered patterns. From these examples\, we see Gaussian curvature emerging as a powerful tool that can generate complex patterns.
