Wales-based sculptor Ivan Black creates large-scale kinetic sculptures that are inspired by mathematical formulae and minimal design. One of his latest pieces, Square Wave, is smaller than his typical works and was designed in response to the Fibonacci sequence. The mobile-like object is made up of several metal bands which curve and flatten as the work twists, creating a mesmerizing movement that is at once fluid and strictly geometric.

The sculpture is included in the group exhibition In the Manner of Smoke at Alice Black Gallery in London through July 7, 2018. You can view more of Black’s interactive designs based on mathematical structures on his website and Instagram. (via Design Milk)
