Cool.  I'll put them up on /lego-robotics if you have no better place.

Thanks!  I hope to get some pictures in the next few days...

There is a minor tweak  I forgot the ratchet on the other axle.
Corrected picture is:

          *     <- Large gear on differential body drives output.
      *-R[]R-*  <- R = ratchet, [] = differential.
      ^         <- 1st gear axle has large gear which drives medium
                   gear as differential input 1.
             ^  <- 2nd gear axle has medium gear which drives medium
                   gear as differential input 2.
      *      *  <- small gears.  Left drives 1st gear axle, right drives
                   2nd gear axle.
-#-//////SSSSS#-M  <- /// = screw, SSS = spring, M = motor (geared down a
                   bit)

It is so cool to add to the load by squeezing a rubber wheel connected
to the output and watch the screw slide over and change gears!
