ABSTRACT:
Color wheel, having an opening provided therein, may be rotated in a first direction to generate a colorful display through a kaleidoscope-type observation tube and in a second, reversed direction to fix the color-wheel opening in alignment with an external opening and the observation tube to bring real-life objects into view. A shutter rotates regardless of direction of movement of the color wheel to simulate the shutter in a movie camera.
