Bent, poked and stretched

It took me a while to find the scale and offset needed to persuade Anim8or's "bend" Modifier to torque a straight tube the appropriate 60 degrees. I'd made a tube with its length the same as 1/6 of the circumference of the desired torus, but most offsets for the bend Modifier kept stretching its outside circumference instead of leaving it unchanged.

Then there's the matter of keeping the spoke from being squished during the bending. Pre-stretching left it all lumpy. :(  I had to cut it off and then reattach it afterward. I think it's a little skinnier than it should be, but I'm not up to resizing it for now.

Celestia has a bug in how it draws transparent surfaces when they're regions of an single mesh which have had a transparent material applied to them: their surfaces aren't correctly depth-sorted. The workaround is relatively straightforward, though: cut them out and paste them into the mesh but leave them as separate objects.
