John Cage planned the installation for the full fourth floor of 500 Sampsonia Way. He made a grid of the gallery floor and walls, and assigned a number to each grid space. A computer program generated random patterns for placement of the wall-hung works and the chairs.
The plan for the exhibition blocked out instructions. Each day the curator hung the 15 works of art and placed the chairs designated by the plan.
Cage provided a script for placement of the wall-hung works.
Cage also supplied a script for placement of the chairs.
