The sketch involves drawing random lines, still constrained by a few pre-defined rules, between dots on a canvas. The pattern of dots is also generated in an arbitrary fashion. Re-execution of the code will result in a different design. I was very interested in the possibility to use this board of dots as a canvas to draw scenes and other interesting patterns.
I tweaked the canvas size to produce a larger image. Personally, it was too busy as a desktop wallpaper and I can probably work around that by tweaking the number of dots and lines. However, I like it a lot more as a browser theme.
