Ion Barladeanu is now considered an important Romanian contemporary artist - but just three years ago, he was living in the rubbish dump of a block of Bucharest flats.

Barladeanu has spent his life creating politically subversive collages in secret, many in reaction to the regime of Nicolae Ceausescu.

He says he considers himself as a 'director' of his collages, which he sees as being like films.

Now, after decades of obscurity, he has been discovered by the art world - and was the recent subject of an Emmy award-winning documentary, The World According to Ion B.

Tom Wilson went to meet the artist.
