I had promised to make another video this weekend of the new Mindsensors GlideWheel-M encoder sensor and behold, the result!  I took a pan & tilt rig I used for a previous project and modified it a bit.  You can see the result below.

The Power Functions motors are so nice and quiet and had no issues turn the rig, even at ridiculously low power settings.
