For decades, the work of Venezuela-born, Paris-based artist Carlos Cruz-Diez has tantalized and transfixed—illusion-like but incisive. The 94-year-old artist’s pieces catch eyes at exhibitions and art fairs the world over for their participatory take on color through space and time. To celebrate this, and their 25-year partnership with Art Basel, UBS built their VIP lounge in Switzerland around their collection of Cruz-Diez art. Many of the pieces were exhibited together for the first time. And the result was a transformative destination that began and ended the famed Swiss art fair as a highlight.
