Minecraft field trip

Anybody seen a fractal in Minecraft?
	Landscapes?  Yes
	Mazes?  Yes (with cycles)
	Trees?  Yes, not too realistic

Worm fractal project again:
	We made it work!
	Cool!
	Can we keep the UI going, and let us see the drawing?
		Yeah, about that

Data structures, and multithreaded changes:
	Sometimes hard to engineer anything good here
	As far as I can tell, Blender doesn't support mesh addition from multiple threads
	Also, our calculation time is really small, and placing the mesh is slow
	Therefore, we'll have to be prepared to wait

But it would be more fun if we could see what's happening!
	thread_doler approach
		Keep tasks in a queue
		Dole them out one at a time with a function
		If we dump them all in, it seems to freeze the UI
			tried it...
	A little gap between tasks will let the UI respond
		Along with appropriately-sized tasks
		worm.py on Nimrod, or recreate it in class
			If I copy the demo over, don't let it not make sense

Biggest question here:  Why is it so slow?
	Maybe we should make our own mesh by placing our own vertices
		Instead of primitive_cylinder_add

Let's try!
	Make a mesh:  bpy.data.meshes.new will return it, can set name
	It'll have a method called from_pydata
		vertices, edges, faces (can infer edges from faces)
	bpy_extras.object_utils.object_data_add(context, mesh)
	This seemed to fix the performance problem for me
		Might import worm_mesh.py for this, since it might take a while

Color on our custom mesh:
	Pretty much the same way

Z-fighting
	Why's it called that even when it's on multiple planes?
	Joinery and caps
