National Portrait Gallery, London, Studio Gallery, Chasing Mirrors, 9 October 2009-10 January 2010
"Chasing Mirrors is an exhibition of new work exploring alternative forms of self-representation and portraiture by contemporary artist Faisal Abdu’Allah and the Chasing Mirrors Collective, a group of young people from Arabic speaking communities in Brent, Barnet and Ealing."
I saw this recently, and found it a very interesting use of multimedia. It's worth catching if you are in London.
