Abstract: A plastic grid or framework arrangement is used to support and position a series of bowls that hold flower arrangements, candles, letters, and other decorative elements. This grid is deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. A special feature of this invention is that the grid itself does not float and is positioned below the surface of the water, and thus is not readily visible. Buoyancy is provided at the hubs that form nodes in the grid. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain.

Abstract: “The Microcosm Terrestrial and Aquatic Landscape Habitat” is a free-standing, fired-clay Topiary structure with Upper Pool, Waterfall and Pond-Aquarium Hybrid. It is built of fired stoneware clay shaped into naturalistic, “para-geological” forms of “miniature mountains” by my art craft. There is an Upper Pool for water on the rear “miniature mountain.” From the Upper Pool, a Water Course leads to a Waterfall constructed of clay, simulated “rocks.” The Waterfall splashes into a Main Catch Basin, a Pond. The Pond is framed by three “miniature mountain” structures, connected together into a loosely horse shoe shape. It is important to note that the gradiently sloping, support structure provided by the “miniature mountains” is a plausible emulation of naturally occurring geologies. In place of a fourth “miniature mountain” to enclose the Pond, the Pond is enclosed in front by a pane of glass ? inch to ¼ inch thick. The pane of glass is adhered to the clay using silicon sealant. The Pond holds water.

Abstract: An aquatic habitat extension device uses a circulation assembly to reversibly maintain a volume of water above the surface of an underlying body of water. The aquatic extension can be used alone or with other similar aquatic habitat extensions that themselves can be varied in terms of size, shape, and the degree to which they are filled with water. Each habitat extension has a water inlet located beneath the surface of a body of water, which preserves the partial vacuum in the aquatic extension, and provides an entryway for aquatic animals to enter the transparent habitat extension where they are observed. To increase the occasions when fish or other aquatic animals enter a given habitat, a food delivery system delivers food to an air pocket trapped in the upper portion of an individual extension. Illuminating or tinting the habitats enhances the beauty of an aquarium, pond, water garden, or other body of water and can be accomplished through the use of a fiber optic cable system or more conventional means.
