Vik Muniz is a photographer. His work is made from diamonds, dust, caviar, thread, wire, dirt, chocolate, and garbage, but he is a photographer. He shapes portraits from the materials listed above only to photograph them, then they're destroyed. Everything was done for the photograph and it only exists as a photograph. I like that. And his work is fucking sweet.
These are his Caviar Monsters
This is a portrait of an Army Soldier shaped by toy soldiers. The picture directly below is a detail.
