. . . it’s from a small selection of images about ceilings (!) I arranged from a recent trip to France. Here a couple more of the natural ones and a sound clip to prove my mother wrong about there being no sounds at night !?!
And here are the real (if not natural) ceilings from the Chateau d’Oiron, an amazing place full of contemporary art and crazy ceilings. These pics were taken on my iPhone.
