Yes, great all around. But I have a question. Those flat belts, if
they are of considerable length, are folded into "figure 8". I wonder
why, to avoid thel flopping around?

I've seen most run straight, like this: http://tinyurl.com/lq2uky4

And some pulleys are 90 degrees off from one another, so they look
like an 8. http://tinyurl.com/kfqvsa6

But I do recall seeing some figure 8s, too. Here's some info for both
of us. Starting near the bottom, with Research Continues:

The answer which makes sense is the directionality. You reverse the
rotation by flipping the belt 180 degrees on one side.
