1. A motion control system controlling a mirror element within an underwater projection system in a water feature, pool, or spa, the system comprising:

  • a first drive mechanism and a second drive mechanism;

    a first cam mechanism driven by the first drive mechanism and a second cam mechanism driven by the second drive mechanism;

    a first input shaft coupled to and driven by the first cam mechanism and a second input shaft coupled to and driven by the second cam mechanism; and

    a mirror support member having a mirror element thereon coupled to the first input shaft, the mirror support member restrained by a first restraint mechanism so as to move about a moment in a first direction by the first input shaft, the mirror support member also restrained by a second restraint mechanism through the first restraint mechanism, so as to move the mirror support member about a moment in a second direction by the second input shaft acting on the second restraint mechanism through the second cam mechanism and the second drive mechanism, and this movement is imparted in the mirror support member and the mirror element mounted thereon which in turn guides an image from the underwater projection system within the water feature, pool or spa.
