Remember the world pre-internet? That’s what Tate Modern is taking us back in time with its blockbuster exhibition Electric Dreams: Art and Technology Before the Internet. The show will showcase how artists used machines and algorithms to make art between the 1950s and the early 1990s, engaging with mathematical principles, early digital tech and new computing systems to produce optical, kinetic and sensory artworks. By displaying pieces made with vintage technology, the exhibition also provides a look back at how artists imagined the visual language of the future.
