AWESOME good looking animation! Just let the wheels turn in the right 
direction...

The wheels turn clockwise when the motive gear turns anti-clockwise? Is this 
an error in the animation or am I missing something? Even going downhill the 
wheels should turn the same direction as the gears.

BTW: here's a link to an animation (less beautiful - more technical)
