if you are referring to the yellow gear assembly part, i have made instructions on how to build that with regular bricks!
if you're talking about motorizing this that would be awesome
i didn't find my LEGO motor. i would so make a mod with the motor just for kicks. not very portable but it would be very cool!
ah yes man! =D this was my first thought, too!
how about adding the motor for "quick-adjusting" ^^
or wasn't there the possibility to program or control this stuff with the PC?
big up to "bad the builder" ^^
