Visual art ...
It's also good for other things.
I was sat there enjoying the water when I saw these bubbles coming up ... ever so sloooowly from the depths of the bath. I remember sitting there thinking - 'Wow. Look at those bubbles, aren't they beautiful. Look how slowly they rise. Beautiful, almost mettalic.' My reflection on the art form continued until the first bubble hit the surface and burst ... literally. I then found myself trying to backstroke away from the immediate area quite quickly.
