Consider the legendary 'Vaults'.
Some are built to house 1,000 women, and only one man. Others, 1,000 men and only one woman. Some are filled with guns, others devoid of weapons. Some are designed to gradually fall apart, demanding that their occupants constantly battle against degrading systems and rusting valves. Some released psychotropic drugs into the atmosphere ten days after the doors were shut. Just to see what happened.
