I just saw this pop up in a Google Search:

If you haven't seen Jay Leno's video of this, it's probably worth watching as well:

These things are very cool, IMO, and quite a bit more difficult to find than the Leno video implies.

 

Never knew it was a rotary on a spider, nice find though.

 

^That was just awesome
