Whilst researching on Christmas and waste, I came across an interesting article on Avso.org : http://www.avso.org/interior-design-ideas/works-of-art-from-garbage-and-waste-of-vik-muniz
Brazilian artist Vik Muniz creates larges pieces of art work from garbage. He is a volunteer at the United Nations who believes that you can create art from any material. Besides garbage he uses other materials such as diamonds, sugars, chocolate syrup and more.
