That's nifty, Tytus. I built something similar this summer, and then drew it up in MLCad. I don't have any of the Lego pnuematics, so I did it all with motors, which was an interesting challenge in itself. The left wedge wheel is the output, and the right goes to the shifting motor.



For anyone interested:

It's huge and unwieldy, but it works, and it's kinda cool.
