1. An assembly for projecting or displaying images on a display surface with motion and high resolution, comprising:

  • a projector receiving an input image stream and projecting animated images based on the input image stream at a projection rate of at least 24 frames per second;

    a mirror assembly with one or more mirrors positionable to reflect the projected images onto a display surface at a plurality of positions, wherein the display surface comprises a rear surface of a rear projection screen; and

    a motor controller assembly positioning the one or more mirrors based on a set of position data defining the plurality of positions,wherein the plurality of positions define an animation pattern on the display surface for at least one predefined portion of the input image stream,wherein the positioning is performed to move the projected images through the animation pattern at a rate greater than the projection rate, andwherein the mirror assembly comprises an X-axis mirror and a Y-axis mirror each pivotable about an axis with the mirror axes being offset and orthogonal.
