I have always been fascinated by Intamin's 'Double/Triple Arm Wheels', like KI's Zodiac. Though I have never seen one of these rides in person I have seen footage of the ones that used to be at Great America and Hersheypark. Those were triple armed wheels, as Zodiac was only double armed and from most pics I have seen it looks as if the whole ride is stationary and doesn't rotate except for the wheels themselves. It looks as if the two wheels move up and down while rotating, but not the main boom itself like the triple arm wheels do, providing spinning in both directions? Hard to describe what I am talking about without having some pics to upload, does anyone have any info on the great Zodiac?

Have a look here to start:
