This is my favourite. It looks like the buildings have been cocooned. The future, it says, in the whispery, cold winded future, we will all be living in buildings that need to be cocooned in fibres to keep the pollution for passing through; to keep the air from we need from entering out lungs and disintegrating our organs with their little touches. We will live in buildings that have more in common with coffins at a funeral than anything that is life.
