How to Make a Pinwheel Pattern

A Gimp 2.8 Tutorial

A pinwheel is defined either as a toy that has a set of thin vanes that are arranged like a fan on the end of a stick and that spin like a wheel when air is blown on them, or as a type of firework that spins like a wheel. A pinwheel pattern is, similarly, a pattern that takes the form of vanes arranged regularly into a circular shape.

This novice-level tutorial describes how to create this pinwheel pattern.
