Wide angle

There have been a few planes/ helicopters over our house this afternoon which prompted me to have a look at the sky ... and I saw quite dramatic clouds, so suddenly thought about my fish-eye lens, which I've hardly ever used.  My first shot was taken in the room where I'm now sitting (I often take this kind of test shot if I change a lens or a setting on the camera).  I think this might be a first - see extra.
