I'll talk about joint work with Sam Taylor.  We characterize convex cocompact subgroups of mapping class groups that arise as subgroups of specially embedded right-angled Artin groups.  We use this to construct convex cocompact subgroups of Mod(S) whose orbit maps into the curve complex have small Lipschitz constants.
