on-the-fly is a Creative Europe project, led by Hangar in partnership with ZKM | Center for Art and Media Karlsruhe, Ljudmila and Creative Coding Utrecht, committed to support the development of the European Live Coding practices. Live coding is a performing art and a creative technique, centred on writing and modifying algorithms in real-time, often in the presence of a physical or virtual audience in such a way, that the person writing the algorithms becomes part of the algorithm itself. This is, live coding explores real-time writing of algorithms with creative intentions. The process is shown to the public, thus giving insights on the performer's mind. Strongly tied to mathematics and computer science, live coding is a powerful tool for promoting artistic research, digital creation and technology literacy. It is mainly used to create sound, music, and visuals, but there are examples exploring fields such as poetry, robotics or dance. By its characteristics, live coding engages with diverse unexplored and novel areas in the creative sector (e.g human–computer interaction and programming language design) rendering the practice an ideal platform for both artistic and digital experiments. Following the spirit of the live coding community, on-the-fly project engages with the free culture movement, promotes self creativity rather than cultural consumption, as well as inclusion and respect.
