Gyula Kosice was a pioneer of Concrete and Kinetic art. In the late 1940s, he co-founded Madí, whose experimental approach led him to use unorthodox materials, such as metal slats, neon lights, and Plexiglas. He wanted to engage the public in playful and dynamic ways. For example, Obra articulada y móvil en bronce has no predetermined shape. The flat bronze slats are riveted at joints so they can be pivoted in various directions, thereby generating any number of potential forms.
