How can mediums be challenged and turned upside down? Not in the result coming from it (in this case a video) but in the way we look at what we do while we do it. In the case of House the movement becomes the essence of a rather still image, just like the paintbrushes strokes become the essence of the movement within a still painting. Humans can be a medium. Movement can be predetermined by space. I can determine the space and thus also movement within it.
