A conical rocker consisting of a sphere at the point and a nearly half bowl form supports a pendulum revolving about the cone's axis. As the pendulum swings a conical arc weight at one end sweeps over the bowl form and above the surface of the granite base. There is a small weight on the upper arm of the pendulum that can be used to alter the pendulums's frequency. As the rocker and pendulum move, energy cycles between kinetic and potential forms and is transferred between the pendulum and rocker. Since their periods of motion are not equal, they move with an interesting rhythmic pattern as one catches up to then passes the other. Moving the small weight on the pendulum will change the pattern of motion of the sculpture. The pattern is also dependent on the initial conditions, angle and velocity given the pendulum and rocker as the observer sets the piece in motion.
