Zusammenfassung:	The disclosure relates to a pointer (12) for a three dimensional display wherein a scanned light beam is displayed upon a rotating display member (1,13) rotating about a fixed axis (2) for receiving and displaying the scanned light beam on a first surface thereof. In response to rotation of the display means fixed points in the display impinging upon the display member to display a harmonic motion along an axis passing through the scanned light beam. A beam of focussed light, preferably from a laser (10) is modulated (11) to synchronize with rotation of the display member to provide a visible point in the display at a predetermined location therein. A second embodiment provides an encoder (9), light conducting rod bundle and sensor (15) to determine the three dimensional location of the point denoted by the pointer.
