If the graviton is the only particle which carries a spin-2 component, then the form of primordial tensor non-Gaussianity (NG) is severely restricted. I will explain how additional spinning species could generate new shapes of tensor NG. The discussion includes exotic de Sitter gauge theories with no flat space analogue, as well as connections to holography.
