By focusing on brief moments of perception and by drawing on my experience as the producer of these events, through acts of parresia and the writing in the text laboratory, which was then contrasted with the more than 2000 documents that were archived in a techno-biographical manner, I conducted an analysis from four different perspectives. A primary analysis consists of reflections in which I share and elaborate upon insights that I acquired as the producer of these events. A secondary analysis deals with the clash between intention and realization that every actor has to deal with. A third analysis concerns the collaboration between people of different disciplines, skills, interests and cultures. The fourth analysis focuses on what can be formulated about natural, mediated and witnessed presence given the research done.
