This script generates rotated copies of the current layer.
It can be used to draw star-like images (see jpg below)
Save the script in your scripts folder, you will find it under Layer -> Transform -> repeat rotation.

These scripts are mainly aimed at generating L-system fractals using turtle graphics. As an added bonus, shapes (not fractals) and turtle trails too.
L-system (or shapes, or turtle trails) can be drawn using different tools, including path, and centered/scaled to image/layer/mask.

Save both scripts in your scripts folder, you will find it under Filters -> Render -> Turtle graphics.

The Script generates a cow-blotches texture.
