Moonlight on the sea at night

It was one of those days when there doesn't seem to be five minutes to take a good Blip. So today I snapped my bathroom sculpture. Sounds very grand, right? I was walking along a beach and I came across a very dark stone and a lovely white stone lying beside each other. Every since they have been known as 'Moonlight on the sea at night'.

Ties in nicely with one of my pet topics ? how much do we construct the world around us?
