My imagination infers a fairy tale family must live inside the NCMA's Cloud Chamber for Trees and Sky.
In reality this work by British artist Chris Drury is a camera obsura devise that projects the sky and trees onto the interior surfaces.
Above is the ceiling and below is where the ceiling meets the inside walls.
Next is a shot I took inside looking out. By the way, I've been inside the Cloud Chamber for Trees and Sky many times but I've never seen anything projected on the interior surfaces, perhaps because of the light during the time I was at the NC Museum of Art Park.
Below you can see the irregular stones on the exterior walls.
