Fractals, review from CS101:
	Mathmatical pattern generation
	We'll look at the one that's already in Python

Output method:
	Could we output something else, say, a cylinder?
		with primitive_cylinder_add
		It'll probably be faster without end caps
			Will that look weird on corners?
			There's a capsule object too
			And we're not stuck with only predefined meshes

Next time:
	Could we adjust where the vertices in a mesh are?
	Color?

Homework 1:  Write a script that makes a caterpillar
	It's a series of segments
	Each segment has two legs
	Look at pictures of caterpillars and do your best
	Make a function that creates segments, and run it in a loop
	Have a variable that indicates the number of segments
