Abstract
An illusory time display system of clock hand or hands in a case too small in radial dimension to permit normal rotation of the hands around the case, provides nevertheless for normal rotation of the hands and accurate conventional display of time. The outer ends of the hands travel in a smoothly contoured channel along the case periphery and collapse axially into themselves by contact with the case as they are conventionally rotated by any conventional drive, to accomplish the apparently impossible non-jamming travel around the too-small case. Various versions of odd-shaped and/or non-concentric timepiece face, case, and hands that further the illusion are disclosed.
