Delegations (2007-2008) is a series of works exhibited in Turkey (Delegation I: "Eigenvekil"), Mexico (Delegation II: "Eigenrepresentante") and South Korea (Delegation III).
Delegation III (Seoul, 2008) is an installation that consists of a projector, a PC and a webcam. The viewers see a processed image of themselves which is constructed using the combination of statistically extracted face features of all members of the National Assembly of South Korea. The difference from the previous versions is that the faces on the screen are detected and only those rectangular areas are processed and reconstructed. This way multiple viewers can interact with the piece.
