Beautiful door.
Created by Matharoo Associates for a diamond merchant in India. It's 17 feet tall, five and a half feet wide, and is made up of 40 sections of Burmese teak. The door uses a counterweight, 80 ball bearings and 160 pulleys to create the effect of reconfiguring into a sinusoidal curve when you push on any one section.
