Water tower

I've long been fascinated by water towers like this one in the Garthamlock area of Glasgow's east end. It's a fairly massive structure and sits on one of the highest points for miles around so you can see it from quite a distance. I've always though there's something fairly sinister-looking about them during the day but at night, this one's a riot of colour as a bank of floodlights at the base gently rolls through a series of colour combinations.
