A hyperbolic flow by mean curvature equation, vt + γv = κ, for the evolution of interfaces is studied. Here v, κ and vt are the normal velocity, curvature and normal acceleration of the interface. A crystalline algorithm is developed for the motion of closed convex polygonal curves; such curves may exhibit damped oscillations and their shape appears to rotate during the evolutionary process. The motion of circular interfaces is also studied both analytically and numerically.
