He's known as the invisible man for good reason.
Whether lurking next to a telephone box or standing to attention in front of the iconic Beijing Olympic Stadium, Liu Bolin has made an art form out of blending in.
The Chinese artist is creating more than just startling images with his works.
He claims they make a statement about his place in society. He sees himself as an outsider whose artistic efforts are not always valued, especially in his native country.
Standing silently in front of his chosen scene, in locations all around the world, the 38-year-old uses himself as a blank canvas.
Then, with a little help from an assistant, he paints his body to merge as seamlessly as possible with what is behind him.
It means people walking by while he is carrying out his performances often have no idea he is nearby until he begins to move.
