Rotating Kink Spacetime in 2+1 Dimensions

A new family of solutions is presented for the (2+1)-dimensional Einstein equations with a rotating perfect fluid source. The mass density and pressure are everywhere positive. Features of the spacetime include closed timelike curves and Finkelstein-Misner metrical kinks.
