Abstract: A system for producing and viewing a three-dimensional/stereoscopic image comprises a two-dimensional substrate having a number of blank regions that has been filled in/colored by a user with selected colors calculated to produce a stereoscopic image when viewed through a stereoscopic viewer. The colored regions are separated by black lines and together operate to form a desired image. The image has a background that is predominately black. The black lines and/or background can be provided before or after the user has colored in the blank regions. When the colored image comprising the black lines and black background is viewed through a stereoscopic viewer, the user perceives a three-dimensional image.

Abstract: An optical effect bubble generating system includes an optical effect viewing device including one or more desired holographic images. The optical effect viewing device can be eyeglasses having lenses containing the holographic images. The lenses can be interchangeable to provide different holographic images. The system includes a bubble generating device that can be manually or automatically-operated. The system operates to provide the optical effect of imposing the desired holographic image onto one or more bubbles when the bubbles are generated in a naturally or artificially-lit environment, and the one or more bubbles viewed by a user through the optical effect viewing device.

Abstract: A system for providing a three-dimensional virtual or fantasy environment comprises a viewing device having anaglyph lenses to provide a three-dimensional viewing effect. The viewing device can be a pair of eyeglasses having anaglyph lenses. The system includes a backdrop that may include a support for attaching to a desired structure such as a wall, floor and/or ceiling. The backdrop has themed or scenic artistry from two or more colors superimposed and offset to provide a desired depth effect The backdrop has a central image with a perceived depth different from a surrounding environment. The backdrop can include a light source to provide further visual enhancement for play. The backdrop may be a two-dimensional image on paper, plastic, fabric, or other suitable material. Multiple viewing devices can be provided to permit play by multiple uses at once.

Abstract: A diffraction toy system comprises an optical viewing device that provides a diffraction optical viewing effect. The viewing devices can be a pair of eyeglasses having diffraction lenses. The system includes a child's play object that includes a light source. The play object can be nonwearable or wearable objects that can accommodate a light source, such as toy cars, trucks, swords, hats, belts, tiaras, and the like. The light source can be a light emitting diode, and the light source can emit colored light. The play object can be a light device that produces a light show. The system can include a number of viewing devices worn by multiple users, and the viewing devices can provide the same or a different diffusion optical effect. Backdrops, with or without light sources, can be includes to provide a further enhanced visual effect.

Abstract: Described herein is a waterslide that includes a sliding surface having a sliding path, and at least one object in the sliding path that includes a stereoscopic image thereon. The stereoscopic image appears three-dimensional when viewed by a user through a pair of three dimensional goggles.
