Awesome bubble created by a large hoop of string drawn through bubble mixture then wafted through the air. This was taken during Etruria Canal festival a few years ago. I love the filmy colours created because the thickness of the bubbles skin is only a few atoms thick and acts like a rainbow refracting the light. A bit like the thin layer of oil you sometimes get on a puddle that causes rainbow colour effects that swirl and create fascinating patterns.

Sky texture

Imagine the sky actually looking like this. What could cause it? A giant bubble of soap with the liquid moving around on the surface like bubbles do. Or strange cloud formations made of gossamer from giant spiders? Maybe it’s just dust and dirt and grease smeared on a camera lens. Imagination is fun. Exploring ideas of how things work is fun too.
