One day, Ryoji Goto happened to notice a wire mesh grid that resembled a repetition of people linked together. This experience gave birth to Diamond Structure (Utsukushi-ga-hara Open-Air Museum), in which he replaced the four-legged carbon atoms that comprise the molecular structure of a diamond with human bodies. It consists of 72 black male figures and 72 red female figures, a total of 144 figures, all stretching their limbs and linking their hands and feet. Combined geometrically in this fashion, emotional relationships disappear, allowing the anonymous people to dance together in praise of their connections and creating a work that is full of youthful energy.
