The most important element of Process [#] is the text. The text is the Process described in English, written with the intention of translating its content into software. The software interpretation is secondary to the text.
The text leaves many decisions open to be determined by a programmer. The decisions must be made using personal judgment, thus the text is interpreted through the act of translating the Process from English into a machine language. Process [#] was translated in [#SOFTWARE] different ways by [NAME] into the [LANGUAGE] language in [YEAR].
The hardware running this software Process is inconsequential. In time, the hardware will inevitably fail. The current hardware was selected to be as robust as is possible with current technology, but contemporary electronics are fragile. If an element of the hardware fails, it can be replaced without diminishing the work. Eventually, compatible components will no longer be available because computing technologies are continually changing. When this event inevitably occurs, a new hardware system will need to be acquired and the software should be rewritten for the new hardware to take advantage of the technical advancements since the original interpretation.

Process 18
A rectangular surface filled with instances of Element 5, each with a different size and gray value. Draw a quadrilateral connecting the endpoints of each pair of Elements that are touching. Increase the opacity of the quadrilateral while the Elements are touching.

Process 14
A rectangular surface densely filled with instances of Element 4, each with a different size and direction. Display the intersections by drawing a circle at each point of contact. Set the size of each circle relative to the distance between the centers of the overlapping Elements. Draw the smallest possible circle as black and the largest as white, with varying grays between.

Process 10
Position a circle at the center of a rectangular surface. Set its diameter to larger than the longest edge. Set the center of the circle as the origin for a large group of Element 1. When each Element moves beyond the edge of the circle, move its position back to the origin. Draw a line from the centers of Elements that are touching. Set the value of the shortest possible line to white and the longest to black, with varying grays between.

// ------------
Structure 2
A grid of points in the top half of the surface. Each point moves downward and returns to the top when it falls off the bottom edge. Beginning in the upper-left, each row and column moves faster than the previous one. The speeds combine so that the point in the upper-left is the slowest and the point in the lower-right is the fastest. Copy and flip the grid across a central vertical axis and display simultaneously.
