Water Tank Fez Tassles

In Cargo Cult land, many of the buildings have sprouted water tanks on their roofs, so that the thirsty natives can quench their slaked tongues and wash the street grime from their sweaty hides.

These tanks are supported by a variety of methods, but they all have a common theme: they look like a bit like fez hats (to me anyway), hence the need (in my opinion) for them to be equipped with tassles.

On stormy days, the tassles will blow around, doubling up as wind-socks. At night they might have trails of coloured leds. They serve no other practical purpose, but then this is the halfbakery.
