While not all of the pieces featured are interactive, the exhibition offers a retrospective view of Colombo’s explorations into physical space and mastery of kinetic art. Spazio elastico (Bianco) (1973), for example, is a wheel-shaped piece made with shaped wood, nails, oil, and metal wire. It comes from his seminal “Spazio Elastico” (“Elastic Space”) series, in which fluorescent strings are lit by blacklight and create disorienting optical effects. Meanwhile, early works like Roto-Optic (1964) represent Colombo’s initial investigations into light and feature electromechanical animation. Alternatively, the foam, wood, and rubber Strutturazione pulsante (Pulsating Structuralization) (1959)—a motorized wall of blocks that pulsates according to a random sequence—represents one of his earliest artistic experiments with kinetic sculpture.
