In his work, Yoon hangs a group of male and female toy-like rubber figures on a strings in a way they all look like they are marching, one by one. Portraying the idea of a group as opposed to an individual, the artist uses light as a metaphor for invisible power and tricks politics use to control the societies. When a viewer approaches, a motion sensor shakes the light bulb, making the crowd’s shadow move around the space. The idea to study oppression and its mechanisms was born during Yoon’s services in the military in Korea. After reading Michael Foucult’s ‘Discipline and Punish’, the artist was analyzing the training methodology for the new troops. “In the end, I felt that humans are weak and fragile, spiritless animals under certain rule, certain harsh conditions,” he explains.
