Abstract: A Christmas tree ornament spotlight that decoratively illuminates ornaments by means of a miniature spotlight. When not in operation, the present invention is itself a tree ornament. When in operation it both enhances the decorative effect of other ornaments and itself has decorative effect, both in its inherently ornamental housing, and in the patterns of the beams of light cast by its spotlight. The direction of the light beam relative to the vertical and horizontal axes may be adjusted and fixed so as to particularly illuminate neighboring ornaments and/or for creating a distinctive pattern of light beams.

Abstract: A retaining wall for remote environments such as wilderness trails utilizes an "H-beam" post member having first and second elongate, vertical plates joined in a spaced, generally parallel relationship by first and second vertical brace portions, so that the cross-section of the resultant construction yields a central cavity between a pair of open web or channel portions. For installation, a stake member (e.g., a segment of rebar or similar material) is driven into the ground, and the central cavity of the H-beam post is placed over the rebar, so that the rebar engages the central cavity and supports the H-beam post. Additional H-beam posts are installed at spaced intervals along the line of the intended retaining wall. Boards, planks or other elongate, sectional materials are inserted into the open webs between adjacent H-beam posts, and are successively stacked to create a wall. Anchors are installed from the H-beam post into the soil or rock for stability. Finally, a cap can be placed on the boards.
