A spirograph is a drawing toy that uses several plastic pieces to draw intricate geometric designs. A few large pieces (stators) are held motionless while other pieces (gears) move around them. The pieces have teeth so that the gears stay in constant contact with the stator. The gears have small holes at different radii. A pen or marker can be inserted into one of the holes to draw the geometric design. A similar device is used to create the geometric designs on paper money because the designs are hard to reverse engineer.

This LoRA is an attempt to simulate spirograph designs. And it appears that spirograph designs are hard for diffusion models to learn, too. But the results are still often interesting in their own right.
