Lucid Stead is a near-invisible desert shack located in south east Californias Joshua Tree national park. Alternating mirrored slats in artist Phillip K. Smiths installation reflect the sand, bushes, and hills of the surrounding desert, contrasting against the gnarled and worn wood that makes the framework of the 70-year-old homesteader cabin. At night, Lucid Stead is illuminated, its windows and door glowing with LED lights that change hue over time. Smith uses the LED lights and the shacks mirrors to evoke subtle transformation, saying Lucid Stead is about tapping into the quiet and the pace of change of the desert. Watch for long enough and youll see the shifts in the Joshua Tree park as Lucid Stead reflects the light of morning, then midday, then dusk.
