Abstract: A real image projection system is provided including a projection system housing with an aperture. This device provides a real image projected into a viewable volume of space relative to the aperture. An optical assembly and an object positioning device adjacent to the optic assembly provide the real image. The object positioning device may position an object adjacent to the optic assembly in dynamic or static fashion. The optical assembly receives the light rays reflected from the object and projects a real image of the object into the viewable volume of space. The invention provides environmental visual cues to promote perception of a three-dimensional image. The invention further includes a secondary mirror for use in reducing or minimizing the overall size of the system housing.

Abstract: A maze puzzle is disclosed employing a concealed maze pattern on one member and a second member movable with respect to the first member and including a pin or follower which engages the maze pattern. A plurality of switches are located in various positions in the maze pattern and are operated as a pin passes each point. A sound generator producing an appropriate audible signal provides an audible message to the player. A similar generator provides a power for visual indicators such as a liquid crystal display or light emitting diode. A key member is either concealed or locked within the puzzle until a certain level of successful performance of the puzzle is achieved. The key may be used to open a secret compartment in the puzzle.
