Since the existence of interacting SCFTs in six dimensions was first inferred by string theory, many have sought a Lagrangian construction of such models. With this goal in mind, in this talk I will introduce some curious supersymmetric Lagrangian gauge theories in five dimensions. These models exhibit an Omega-deformed non-relativistic conformal symmetry, and have a single, discrete coupling. Crucially, I will argue that these models in fact capture the dynamics of six-dimensional (2,0) and (1,0) SCFTs, through a solitonic enhancement mechanism analogous to that of the ABJM model. I will finally speculate on the utility of the models, including through the fashionable paradigms of integrability and localisation.
