Human-Computer-Interaction provides a possibly infinite potential for artistic creation. From the textual algorithm basis (in common with former media such as writing), visual and sound languages can be constructed that provide a framework for the user to work with (for example, graphic design software). Specific programming languages or even physical installations can be arrange, providing numerous occasions for endless combinations of creation involving a person and a computer. The constrains of the computer language and software can be actually become a potential, as they restrict the potential entropy of limitless creation from too-open systems. Artistic creation and computing overlap and transform each other.
