Liu Bolin paints his body, or that of his subjects, into an illusion of invisibility for his photographs of his native China. This could have ended up being a pretty shallow artifice, but I like the way he puts it to use to create a sense of the invisibility of the individual in contemporary China (here), the complex relationship with the Chinese state (here and here for a couple of examples) and its slavish devotion to incessant economic development.
