Vik Muniz says he owes his artistic career to being shot as a young man, not because he had an epiphany about the meaning of his life, but because he won enough compensation from the accident to move to New York and kick-start his career in the art world. He is now probably one of Brazil’s most successful visual artists and his pieces can range from tiny specs that are photographed by microscopes to giant landscapes captured from helicopters. He is known for working with unconventional materials; some of his most famous works have been created out of sugar, chocolate and a plate of left over spaghetti. Andrea Kennedy went to New York to meet him as he prepared for an exhibition full of illusions.
