Most of my computer generated artworks arise from visualizations of biological or mathematical processes. I want to focus the viewer's attention on the complexity and intricacy underlying such processes.

In general, avoidance drawings arise from several virtual drawing robots (drawbots) executing random walks based on curvature via a model introduced by Chappell subject to the condition that they may cross only their own paths. In Doubly Intertwined two drawbots avoid the canvas boundary, eight invisible barriers and each other but also have a tendency to follow nearby segments of each others paths. As a consequence, the two resulting complexly, intertwined drawbot paths are independently contractible to their respective starting points.
