This is Lucid Stead, an art installation by artist Phillip K. Smith III. A 70-old homesteader cabin sits on Mr. Smith’s property in Joshua Tree, California. He removed sections of wood siding and replaced them with mirrors.
When you look at Lucid Stead during the day, it appears that you can see right through it, thanks to the reflection of the desert landscape. During the night, interior lights create a show of ever-shifting colors. Mr. Smith writes that observing Lucid Stead is an opportunity to share in “the pace of change of the desert.” You can see more photos and videos of it here.
