crazy door

designer: Matharoo Associates
client: a diamond merchant in India
Burmese teak in 40 sections
1 pivot, 1 counterweight, 80 ball bearings, and 160 pulleys

Push on any one plank, and all 40 sections reconfigure themselves into a sinusoidal curve, revealing an opening into the house.

Also, push on any plank and you will totally freak out.
