Jurgen Ostarhild,  born 1956 in Überlingen, is a Berlin-based visual artist and photographer who uses light and code as his canvas. He creates image automata, site-specific installations, multiples and printed artifacts to investigate the boundaries of concrete visual language in the post-photographic landscape. His current work explores distributed data networks such as public blockchains to generate real-time performances of encoded light drawing from the tradition of American color field painting and concrete art.
