I will discuss a notion of convex cocompactness in real projective geometry, which generalizes the usual notion in hyperbolic geometry (joint work with Danciger and Guéritaud). One interesting feature is that convex cocompact groups in this sense need not be Gromov hyperbolic. I will explain how to construct many examples using Coxeter groups (joint work with Danciger, Guéritaud, Lee and Marquis).
