What if modernism had been characterised by evolving, interconnected and multi-sensory images - rather than by the monolithic objects often described by its artists and theorists? In this groundbreaking book, Charissa Terranova unearths a forgotten narrative of modernism, which charts the influence that biology, General Systems Theory and cybernetics had on art in the twentieth century. From kinetic and interactive art to early computer art and installations spanning an entire city, she shows that the digital image was a rich and expansive artistic medium of modernism.
