Lineart.
Parameters and Behavior Schemes:
Similar to the windmill in that it only outputs in 30° increments, but is controlled by direction rather than length.
Comments on use:
This one comes very plain - just have fun with the parameters. Added a bunch of examples to the demo - if you have any questions I'll gladly answer. The spurs come from sharp turns and a low shape interval. One thing not shown is it makes a funny bokeh effect using big square shapes, low opacity, and image-based color.
Hope you like it.

Here's a goofy doodle I did to test it out...
