Venice is hosting the 50th La Biennale arts festival, and this week's 'culture vulture' describes how the city itself becomes a temporary work of art.

Also on the programme: Art's 'enfant terrible' Damien Hirst takes presenter Mark Coles on a trip to Slovenia to look round his latest exhibition. Nigeria's Chinua Achebe talks about colonialism and the need to address the balance in Africa's favour.
