United Visual Artists are an art and design practice based in London and working internationally. They create work at the intersection of sculpture, architecture, live performance and digital installation. Their initial work in live performance led to a sustained interest in spectacle, the relationship between passive spectation and active participation, and the use of responsive systems to create a sense of presence. Almost ten years in its existence, UVA developed a recognisable style, bringing to public installation domane tricks and scale of life performance and vice versa. From the very beginning UVA’s ambitions and ideas were slightly ahead of available technical solutions, therefore in order to fulfil their vision UVA developed custom software and hardware bundle, today referred to as d3.
