Volten was an artist who often built his works from simple shapes, such as the cube, column and sphere. He was progressive in his use of industrial materials. For example, he started working as a welder at the shipyard in Amsterdam-Noord, so that he could fully experiment with steel. With his sculptures he made an important contribution to the development of art in public spaces in the Netherlands. In 1976, Volten created this work of art with a total surface area of 40 by 40 meters, made in the percentage scheme for the new construction of the Municipal Drinking Water Supply (DWL), where Evides is now located. The project architect was the Dutch architect Wim Quist (1930-2022). The work of art consists of a series of eight hook-shaped corten steel objects, which are shaped and bent in different ways, creating an exciting spatial work. The work was on Evides' own premises, making it difficult to see from street level. But from the west side of the Van Brienenoord Bridge, the work was visible until 2023. Due to the expansion of Quist's building and the construction of a parking lot, the artwork was removed and dismantled in 2023. The work is in storage awaiting a new location.
