Two of the simplest singularities, the crosscap and swallowtail. The former arises, for example, in projections of surfaces in higher dimensions to 3-space, in families of projections of a space curve to a plane, and in boundaries of solution sets to certain differential equations. The latter in duals of smooth surfaces, families of plane wavefronts and caustics in 3-space. Their occurence in a wide range of applications is typical.
