Riffing on how film noir protagonists struggle to make sense of their broken and corrupt worlds, Lawrence Lek’s “NOX” opens in Berlin. The speculative filmmaker’s largest show to date, Lek presents a facility where Farsight Corporation, a fictional AI conglomerate, train and service sentient self-driving cars. Exploring Kranzler Eck’s multilevel layout, visitors consume film, sound, and videogame-based works to piece together an elaborate narrative about a rogue self-driving car and therapy bot.
