Simonsong is a video piece, a musical system that exists only through a visual process, in this case a mockery of technological hegemony in the arts, and particularly in the world of contemporary music. In the most trivial representation of the digital tool, up to 16 384 "mousists" (plastic mouse interpreters) play virtuosos in the way of the child's game Simon. Desktopsongs is a cycle of video pieces questioning our relationship with technology. Each work, inspired by desktop movie practice, is a musical system dependent on a visual process. The cycle includes Screensong, questioning data collection related to privacy, Simonsong, questioning technological hegemony in the world of contemporary music, and Playpausesong, questioning mass media consumption.
