Wu Houting has always been interested in the gaps between neighboring objects. He believes that fillers between objects also have their own space, shape, size, distance and turn. He transformed selected fillers into solid entities with different materials. The gaps between objects began to have concrete structures, forms and existence. Wu Houting doesn’t just reproduce invisible parallel spaces. He is more like an architect, carefully designed, reassembled, integrated, polished and shaped those spaces. The final presentations are well reconstituted space entities beyond anticipation.
