His Face Is His Canvas
Artist Levi van Veluw (LAY-vee vahn FAY-loo, roughly) creates works of art on his head. He paints it. He covers it in pebbles. He sets up a model train set to travel around the circumference of his dome. The work makes us think about a person's mental environment as terrain itself and the solipsism of our inescapable subjectivity. Other interpretations: totally valid.
His portfolio is here. We also recommend this video. Thanks, Craig.
