You caught me...I was going to be lazy; animation is a real challenge for me, and that group of gears was particularly difficult so I was going to keep them static, but that wouldn't be true to the skin, now would it? So...I fixed it. They are now spinning.
You didn't have to go that far, but I'm glad you did. I didn't know what was supposed to be animated or not; I just reported what I saw.
Thanks for fixing the scroll bar.
