That looks cool the gear teeth running in opposite directions is creating a neat effect. It looks like the front faceplate is connected to the back gear and the front gear is is independant and spins on it's own on the shaft. Now i can see how you can make the faceplate and backgear spin in one direction with the motor but wouldn't you have to have another gear to turn the front gear in the opposite direction?
In other words your motor and shaft is NOT going to turn the faceplate and backgear in one direction, while turning the front gear in an opposite direction, correct?
