"This interactive interventions is exploring the intersection between new techno- logies, urban space, active participation and alien memory. The Schouwburgplein will be transformed by the projection of huge interactive portraits on the façade of the Pathé Cinema building. Over one thousand portraits - which were taken on the streets of Rotterdam, Madrid, Mexico and Montreal - will be shown, using robotically controlled projectors located around the square. However, the portraits will only appear inside the projected shadows of local passers-by, whose silhouettes will measure between 2 to 22 metres high, depending on how far people are from the powerful light sources placed on the floor of the square. When no one is walking past the Schouwburgplein the portraits cannot be seen, since the light sources on the floor completely wash them off with strong white light. As soon as someone walks on the square, his or her shadow is

 

projected and the portraits are revealed within it. A camera-based tracking system will monitor the location of the shadows in real time, and when the shadows match all the portraits in a given scene, the control computer will issue an automatic command to change the scene to the next set of portraits. This way the people on the square will be invited to embody different representa- tional narratives. Up to 80 people can take part at any given time, controlling 1,200 square metres of projections and creating a collective experience that nonetheless allows discreet individual participation. The shadow interface is a direct reference to Samuel van Hoog- straten's engraving "The Shadow Dance" which appears in his "Inleiding tot de Hogeschool der Schilderkunst". This engraving, made in Rotterdam in 1675, shows a minute source of light placed at ground level and the shadows of actors taking on demonic or angelic characteris- tics depending on their size.
