On Thursday 12th September, Rafael Lozano-Hemmer, an artist participating in the International 2002 will transform Liverpool city centre into a giant open air interactive cinema with his latest project, Body Movies.

Co-commissioned by FACT, this spectacular interactive artwork features over 1,200 large-scale portraits - including some of people taken on the streets of Liverpool - projected onto a 20m x 20m screen in Williamson Square.

Body Movies will run from 12 to 22 September only, from 9.00pm ­ 12.00am. The artwork can only be viewed at night.

Body Movies features portrait photographs of people from Liverpool, Rotterdam, Madrid, Mexico City and Montreal. These portraits are projected onto the 400m-square screen, but only appear when the shadows of passers-by, which are recorded as they walk past, are projected back onto the screen.

The silhouettes they create ­ which can be up to 20 metres high - reveal the portraits hidden underneath. A complex technical artwork, Body Movies incorporates database-driven technology that combines the stored portrait images with the images of people walking by to create a constantly changing display.

Mexican-Canadian artist, Lozano-Hemmer has been commissioned by FACT, the Foundation for Art & Creative Technology, and Liverpool Biennial 2002, to present this work within Liverpool city centre.

FACT is one of the major partners in the Liverpool Biennial, with Lozano-Hemmer's work one of five projects commissioned and selected by FACT for International 2002.
