Tate Modern has opened a major exhibition dedicated to the visionary Argentine-French artist Julio Le Parc (1928-2026), organized in close collaboration with the artist and his Atelier. The show features over 60 works spanning his 70-year career, including interactive installations, light sculptures, and geometric abstract paintings. Arranged in a maze-like layout, the exhibition traces Le Parc's mission to activate viewers through optical effects, sensory experiences, and physical participation, from early black-and-white gouaches to his iconic luminokinetic works like the Continual Light Mobiles. Highlights include the room-sized installation *Vibrating Light – Tulles 1968*, a new large-scale *Continual Light Mobile 2026* in the Blavatnik Building entrance hall, and participatory pieces such as *64 Reflective Blades 2017* and *Game Room* installations.
This exhibition matters because it offers a comprehensive retrospective of Le Parc, a pioneering figure in kinetic and Op art whose work challenged passive spectatorship and anticipated participatory and immersive art trends. By emphasizing the viewer's role in completing the artwork, Le Parc's practice remains highly relevant to contemporary discussions about audience engagement and the boundaries between art and experience. The show also highlights Tate Modern's continued commitment to showcasing influential but sometimes overlooked modern masters, and the acquisition of Le Parc's *Blue Sphere 2001-22* underscores his enduring significance.
