Aumuellers jigsaw puzzle pictures are results of a multistage production process. Expressive, partially with strong auto-lacquers created paintings form the basis. Aumueller then takes photos of these abstract color experiments and cuts these photos by machine into jigsaw puzzles. Afterwards he reassembles individual parts, whereby the original parts produce a new picture in a new composition. At first sight the jigsaw puzzle pictures appear as a "pleasant idea": The result of time-consuming artistic creation is presented as a well-known game for children and adults. This appears to be an ironic move by Aumueller. However, irony is not the artist?s concern. There is more to the jigsaw puzzles than just a nice conception: Aumueller labels his jigsaw puzzles "unstable equilibria" - a suitable description for many things in a world which in many ways appears to be stable and arranged. The jigsaw puzzle is more than just a means of formal expression. It is metaphoric message as well as a clue to the artistic intention.
