On va tous y passer is an interactive video installation set in a transit space. A camera films the area where the installation is located. A monitor displays this video image in real time in a manner of surveillance equipment. This image is however altered so that some of the passersby present on the premises disappear. On va tous y passer is intended to trouble the perceptions of the passerby in public spaces in order to instil doubts about the physical reality, about the "concreteness" of the others.
