This is a Tedtalk by Vik Muniz who is an artist I became really interested in after I watched a documentary about him last semester called Wasteland. He creates all of his work using really creative material. What I like most are the portraits he does made of substances that are relevant to the lives of his subjects (i.e. sugar for children who grow up working on sugar plantains, and trash (not mentioned in this tedtalk but in Wasteland) for people who work picking recycling goods out of a landfill in Brazil. I also like this video because it's always really interesting to hear how very famous artists started their career.
