What is this aborginal doing in my bed?

In 2003 I finished my study at the Academie of fine arts in enschede NL. My final work there was an installation called "what is this Aboriginal doing in my bed". Two main ropes were form the main connection with the Roof. These prove a space resembles to a spider net. All space in between are connected with silver foil and stone tape. Inside was a box from that was a cardiac sound was to be heard. The ground was laid out with a silver foil. In the back part a ring from wood and paper on which a back projection was to be seen was hung up. On the video a selfppotrait of me was to be seen.
