Simple module that makes gears with circular-shaped teeth. The gears maintain their shape even for extremely low teeth numbers up to 2. Parameters:

• teeth: number of teeth.
• step: width of one teeth (diameter of the circle).

Two gears produced with the same step will transfer movement, so one typically fixes a step for all the gears and varies teeth for each gear, which decides the radius and transfer ratio. Example:

A tip: use an extra-long duration (-d 100), record your shot, and use
gimp to shorten the duration of the last frame. You need to rename the layer
from "Frame 123 (100000 ms) (combine)" to "Frame 123 (1000 ms) (combine)".
