I did not know that this existed. This is a sculpture in the town of Seltjarnarnes, practically a suburb of Reykjavík. The sculpture’s name is Kvika and was designed by Ólöf Nordal and erected in 2005. It has a constant flow of hot water intended for foot baths or playing kids. Apparently you can cram a person in it as well. This is in within a healthy walking distance of downtown Reykjavík.
