In this article we present the research of SArt project at the Norwegian University of Science and Technology. In SArt we have the vision that software engineering can benefit from multidisciplinary research at the intersection with art for the purpose of increasing innovation and creativity. The group participates in the development of several interactive art installations and studies the issues and problems in this particular domain. Our findings show several peculiarities of the software development projects which require further study from software engineering perspective. Furthermore, we observe that some important software engineering concepts, like testing and maintenance, which are recognized as important in contemporary software development, are often underestimated in interactive installation art.
