“Interaction Painting“ is a painting method documenting the decisions and reactions of two artists working collaboratively. Every step of creation causes its consequences and becomes part of a dynamic logic. This logic is evolving durching the process of creation. Michael Sebastian Haas and Christian Kera Hinz painted „Layers of Logic I and II“ in September 2016 as comissioned wallsize artworks for a private office. They show logics merging and materialising. The first two interaction paintings are sensitive plays between possibilities and decisions in artistic creation. The process has several stages. First lines are applied with a specific drawing machine. Crossing lines are proposing fields which can stay merely possibilities or become realised as fields of color. The definite color, position and proportion of these fields are telling the visual code which they follow. In fact these lines and fields make the painting a readable structure.
