Plaza water fountains, also called pavement fountains - a grid of individual fountains that rise, fall and stop altogether - have become something of a cliche in cities across the world. There are multiple examples in Britain such as this one in Peterborough and this one near King's Cross, London. We recently came across a further example in Birmingham in Centenary Square. Unlike others, when this one stopped a large area remained covered in a shallow film of water. I don't know whether this was intentional or not but it certainly provided good reflections of passers-by.
