The Spheres is an installation in the form of a large-size urban forest, located at the intersection of two arterial roads in the city of Riyadh. On top of steel-slat trunks, the iron spheres that simulate the crowns of trees are lit up with the colors of the Saudi Arabian flag and have a visual effect on hundreds of people each day. The Spheres has become a benchmark artistic figure for the city.
The installation consists of 27 structures in the shape of different-sized trees, with three different diameters of crown (5, 7 and 9 m). The spheres were created using revolution helicoids, forming a spiral repeated five times. Despite their apparent light weight, they are very heavy structures, each weighing more than 18 tonnes. Rayon used custom-made SHOT LED luminaires to light the base, the trunk and the crown of these trees.
