In a projection arrangement with a projector and a deflecting mirror in which the image projection, proceeding from a projection direction along a principal projection axis impinges on the deflecting mirror which is supported so as to be movable in two spatial direction and whose mirror surface deflects a projected light bundle at an elevation angle and at an azimuth angle onto a projection surface standing on the ground the image projection is effected from the direction of a zenith at an angle &bgr; which is less than 60° in relation to a vertical line from the zenith and the deflecting mirror is arranged at the ground wherein the projected light bundle can be deflected toward the projection surface so that an image can be generated on the projection surface and moved on the latter.
