Gordon Matta-Clark came up with the word "nonuments" to describe his "detournement" position vis-a-vis the monument. This is a point of tension between formalizing the emotion of in-situ demarquation and the actuality of being.

You talk about that uncomfortable tension in terms of documentation. Referring back to Baudrillard isn't all media "performed" nowadays?

I know that I can't do straight video performance art without acknowledging the media-sphere and the segmentation/sampling/repetition of post production.

Actually it makes a lot of sense to create an exhibition that is about making objects. In the art world the object is central player. Think about this. The trend in the US has been away from making things; It's to ship manufacturing to cheap labor markets. Pretty soon there won't be anything made in the USA. Will people forget how to make things? Many postmodernist have other people manufacture their work.
