Pentimento was produced as an Interactive Video Installation and Interactive DVD-ROM during Dennis Del Favero's on-going Research Fellowship at ZKM which began in 1998. The Interactive Video Installation comprises an 8 metre square room with integrated vision based motion detection system articulated to a computer narrative database which interacts with the viewer's movements. The results of these interactions are delivered across four separate projection and five discrete acoustic systems within the installation. The project explores a news report detailing the discovery of an unidentified body in bushland on the outskirts of Sydney. A young man and woman are arrested. They accuse each other of murdering their father whom they allege was sexually abusing them. The viewer's interactions evoke a large scale evolving memory whose fragments comprise the separate narrative fragments of each of the protagonists - father, brother, sister and the crime scene itself. Each of the four separate projection and acoustic systems can be operated both independently and in synchrony with the others in a number of diverse and complex scenarios. In each of these scenarios the viewers precipitate different memory modalities as they attempt to resolve the circumstances of the murder. In attempting to find a resolution nagging difficulties emerge for the viewers. Some of the memories suggest that the father may not be the murder victim but is one of the perpetrators. Other memories suggest that all three protagonists may be dead and the viewers are navigating a violent narrative amongst the dead. (Dennis Del Favero)
