  We go "back to basics", studying accelerating systems in $2+1$ AdS gravity
\textit{ab initio}. We find three classes of geometry, which we interpret by
studying holographically their physical parameters. From these, we construct
stationary, accelerating point particles; one-parameter extensions of the BTZ
family resembling an accelerating black hole; and find new solutions including
a novel accelerating "BTZ geometry" not continuously connected to the BTZ black
hole as well as some black funnel solutions.
