Paper Space
These plotter drawings involve algorithms that treat the paper as space and ink as object. Part of the larger and ongoing project that explores "Computing Drawing", this work structures line in terms of behavior and appearance. The database of all Computing Drawing work to date is online here.

Marks are made by a particle “walking” in a random but generally curving path within a boundary on the page. Marks gradually decrease in length and avoid intersection.
The broadest structure of line in this series is the “walking” path. The secondary structure consists of each “step,” which is in turn structured by a series of marks separated by a proportional spacing. The path maintains a reference to the current trajectory and angular acceleration.
Each step line is created based on the current trajectory and angular acceleration. The angular acceleration becomes more extreme as necessary to avoid intersections of the mark lines. As a result, the “path” appears to cross itself only at the gaps in its own consistency.
A line is drawn at a random angle that will not intersect any previously drawn line. This line is defined in terms of a start point and an end point. Lines of the same length are drawn slightly offset from the previous line. This process is repeated until the new line intersects with any other line, including the boundary lines. If the line slopes upward, its end point is adjusted to the intersect point. Otherwise, the cycle of repetition is broken and a new line is drawn at a random position and angle.
