I noticed the link from the recent TechnoKat thread that led me to a video of 857's kiwi drive from a year or two back.

This thing is increible!!! I've watched the video several times over, and have spent some time trying to figure out how you guys controled it. I just don't see how it could be done with simple joysticks. PLEASE explain to me how you acomplished this incredible task.
This is by far the coolest drive system I've ever seen!
