A single light sphere is placed inside of a drum completely filled with a viscous fluid. the drum rotates perpendicular to gravity such that the Reynolds number remains small. In this flow configuration there is a wide range of behaviours. We have measured eccentric fixed points, circular orbits and asymmetric orbits by the walls of the drum. A full description of these phenomena is given as a function of the size of the sphere. We have also studied the case of a porous sphere and compared it the solid case. Finally we have studied the effect of roughness on this system.
