This meant that our work had already been identified as falling within this field, the definition of which, at the time very uncertain, was the subject of active discussions. Although they have gradually become clearer over the past quarter of a century, its limits remain relatively vague, particularly with regard to its status in relation to other artistic fields such as art/science or digital arts. However, as is the case for many creators-researchers, the retrospective analysis of the projects conducted by our laboratory reveals several elements likely to contribute to clarifying the objectives, methodologies, and frame of reference of research-creation. This is the case for the artistic exploration program Point d.Origine, the subject of our work for several years. Its central element is a small object called the Harmonic Lantern, whose design and implementation took place at the confluence of scientific and historical research, technological development, and creative experimentation. This article describes the origins and challenges of the program and summarizes the steps that led to the Lantern’s final design.}}
