Artist Vik Muniz journeys from to his home country of Brazil, and to Jardim Gramacho, the world's largest garbage dump located on the outskirts of Rio de Janeiro. There Muniz photographs an eclectic band of catadores -- pickers of recyclable materials -- and works with them to "paint" their portraits using garbage. The resulting collaboration with these inspiring characters provides profoundly moving evidence of the transformative power of art and its impact on the human spirit.
