A shimmering glass needle that impales the Melbourne sky, anchored to the earth by the ghostly, reconstructed shell of the 19th-century Celtic Club. Inside, a three-story “indoor forest” breathes oxygen into the lungs of a digital tower, trapping a piece of the wild Australian bush within a climate-controlled sanctuary. It is a vertical maze where only six souls share a floor, staring out through champagne-tinted grids at the city below like high-altitude observers in a velvet cage.
