Bendable Door by Matharoo Associates
What an incredible door - Matharoo Associates of India created this remarkable Teak door, which almost appears to bend open with a tug at the handle.

How does it work:
'The DOOR, to a diamond merchant's residence in Surat, India is at 5.2m high and 1.7m wide. The door comprised of 40 sections of thick 254mm Burma teak where 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.'
