I could see this a a potential DIY project - paint bulbs black and then carve some of the paint off to let the light shine through. While not specific for outdoor use, these Astral Lights would be a lovely addition to an enclosed porch :)
Paint tree branches with metallic gold or silver spray paint and use them as holiday accents around the house! Paint white and hang Aqua Christmas bulbs from branches. place in silver urn or vase, or in clear vase filled with sand.
