Ever since electricity became ubiquitous artists have been fascinated by the manifold possibilities to create works with it. This catalog, accompanying the opening exhibition of Kunsthalle Praha, Kinetismus - 100 Years of Electricity in Art, explores how electricity has transformed artistic practice from 1920 to the present day, including cinematography, sound, kinetic and mechanical sculptures, computer-based art and immersive installations. A historical perspective emphasizes the fact that electricity, with its various usages - from artificial light to computing - has become a defining element of our societies.
