A methodology is provided for build-up of a variety of aesthetically pleasing highly ordered patterns which may, by known print processes, be applied to cover the entire spherical surface of a ball used in a computer input device, to thereby render the ball optically trackable with known optical tracking engines. While highly regular in order and appearance, the patterns resulting from the inventive methodology have an inherent or natural geometric variability permitting the patterns to be tracked without aliasing effects and associated cursor jump or skip encountered with previous attempts to optically track a regular arrangement of pattern elements.
