When viewed from outside an Issey Miyake store in Tokyo, the blue chairs installed in the shop’s window by Japanese architect Yoichi Yamamoto appear to be just another collection of ordinary chairs, but in reality, they’re just wooden backs fixed to the floor – it’s the legs painted onto the ground that, from a fixed angle, appear in the correct perspective and make the chairs look whole. The installation is called 2D/3D Chairs.
