Great idea, shame about reality

This remarkable sculpture is actually a water fountain, in Hyde Park near Marble Arch. Designed by David Harber, it clearly mimics the shape of the world and ties in neatly with the theme of water. It has outlets at all levels, and a place for filling up water bottles. It's been there for almost six months. Unfortunately it no longer works. I'd like to think that it was switched off for the cold weather, but somehow I doubt it.
