A group of artists by the names André Tempel, Christoph Roßner and Annette Paul, have kitted out a wall in Germany with funnels, enabling it to play music as water flows through it.
Called the Neustadt Kunsthofpassage Funnel Wall, this façade consists of inter-connecting funnels and water spouts, allowing the water to flow through them, creating a wide variety of sounds.
The bright blue exterior also makes the building a lot more cheerful, adding to its novelty.
