Process 4 (Installation 1) is a two-channel projection based on the Process 4 text. The text follows:

A rectangular surface filled with varying sizes of Element 1. Draw a line from the centers of Elements that are touching. Set the value of the shortest possible line to black and the longest to white, with varying grays representing values in between.

The definition of the Element and related instructions are in the Process Compendium.
