... and the one most likely to crush little children's fingers. Curtain Door, Surat, India by Matharoo Associates
At 5.2m high and 1.7m wide, the door is comprised of 40 sections of 254mm-thick Burma teak. Each section is carved so that the door integrates 160 pulleys, 80 ball bearings, a wire-rope and a counter weight hidden within the single pivot. Stacked one above the other in the closed position, each plank can then rotate by a simple push causing the door to reconfigure into a sinusoidal curve.
