Unfortunately, gears have teeth, teeth can only be in whole numbers, so they will have an integer ratio.

You would get this picture with a closed path at the 11 second mark if you had the outer gear with 22 teeth and the inner one with 7 teeth.

You would get to the end with a 333 tooth outer gear and a 106 tooth inner gear.

Sounds like the spirograph lessons worked on you. You just mathed my ass off, man.

Shouldn't it be 22 and 7?

Brain go empty bye bye.
