Underwater?

Walking past Salts Mill to the main entrance, I noticed the windows have been lined with some kind of clear film, perhaps to insulate them or to block UV light from spoiling the artworks inside. I can't say I've noticed it on the inside but from outside you can see that it has not adhered uniformly and there are lots of streaks and bubbles. I became fascinated by them and took lots of photos. They gave me the impression of an underwater scene, with weeds and fronds drifting.

Back home, I've been playing with them to create collages. It's a very absorbing pastime, rather addictive!
