Louisville artist burns wood art using only sunlight
Billy Keith has spent 16 years refining a technique that concentrates solar energy through a lens to create freehand designs on timber.

Louisville artist Billy Keith works with a tool he cannot hold in his hand: sunlight. He describes himself as the sun man, a title he uses when meeting new people. His method relies on a large Fresnel lens to concentrate daylight into a single, intense point of heat. This focused beam burns designs directly into wood surfaces without the use of electricity or traditional heat sources.
Keith developed this specific skill over a period of 16 years. He stated that the time was necessary to achieve the speed and smoothness required to execute the work repeatedly. The process demands constant movement of the light point across the wood. When he makes a mark he did not intend, he continues working rather than stopping to correct it. He referred to this approach as a happy accident, keeping the creative flow moving forward.
The artist began this practice after a near-death experience during an Easter weekend. He attributed the event to a night of heavy drinking. During that experience, he heard a whisper instructing him to stop drinking and create art with the sun. He believes he was saved specifically to perform this work. He described the mission as a duty he must fulfill.
Keith produces a variety of subjects, including trees, landscapes, animals, and plants. Each piece contains a specific narrative. One example he shared was a drawing commemorating the day he saved a cat from a tree. He works entirely freehand, avoiding stencils, printers, or other shortcuts that might standardize the output.
He sells his completed pieces online and travels to regional events and festivals for public demonstrations. He prefers working in front of an audience because it allows him to discuss the process with onlookers. The technique is not limited to warm months. He confirmed that he can produce solar art in winter as long as the sun is visible.
His materials list includes standard wood and a Fresnel lens. He also uses bingo dabbers to paint his work. He discovered this tool after finding one on the street. His website, solarcombustion.art, provides access to his current portfolio and contact information for commissions.
Keith operates out of Louisville, Kentucky. His work combines optical physics with traditional woodcraft. The resulting pieces show charred lines that form detailed images on the timber surface.
