In the sculptures made of nickel silver and bronze by Roberto Cordone organic resonates, although they are precisely calculated form connections, in which mostly different circle segments merge with each other. The artist distinguishes, among others, the work groups "Movimenti Elicoidale" and "Movimenti Geometrici". The series of works "Movimenti Elicoidali", created since 2000, is characterized by the fact that the sculptures do not have a binding basis, i.e. they can be placed in different ways. Thus, the sculptures challenge the viewer to interact. Dancers recognized early on that playing with these works by Cordone represents an artistic challenge for them. The sculptor's collaboration with the dance companies of Düsseldorf (1990) and Gelsenkirchen (1992) was therefore logical and resulted in an impressive document of Cordone's work in the 1993 television film "Heavy Metal and Light Steps".
