The fountain is an ode to the world-famous Franeker-born astronomer Jan Hendrik Oort. His assumption that there is a 'cloud' of billions of comet-like objects moving around our solar system marked a breakthrough in astronomy. The fountain is designed as a series of waterfalls flowing from a bowl down a vertical chain of night-coloured pearls into the basin. One of the pearls is silver, like the colour of the moon; another is gold-plated, like the colour of the sun. 'The Oort Cloud' itself is a mist of fine droplets falling from a gold-coloured mesh into the bowl.
This fountain is part of the 11fountains: eleven fountains in the eleven Frisian cities, designed by eleven artists from eleven different countries. 11fountains is an international art project for Leeuwarden-Fryslân 2018, Cultural Capital of Europe, conceived and curated by Anna Tilroe.
