Influenced by Constructivism and the Bauhaus, Lygia Clark is in turn remembered for her impact on various art historical movements, especially as a pioneer in participatory art. During her early career in the 1950s, Clark produced geometric, system-based paintings and Constructivist-influenced sculpture. Shortly after, along with artists Amilcar de Castro, Franz Weissmann, Lygia Pape, and poet Ferreira Gullar, Clark co-founded the Neo-Concrete movement. Around this time, she created her iconic “Bichos” (Beasts), metal sculptures that viewers were invited to rearrange. In the 1960s, her work took a conceptual turn as Clark began to create ephemeral and mutable objects. Her late work continued to investigate sensory perception and interaction along themes of psychotherapy and healing.
