I used a pico dolly and an educational pulley set to make a time-lapse dolly. This is the first video I made with it. Its not that exciting but it shows what the dolly can do.
Here is a link to my blog post with photos and details of the construction of this rig: http://webiocosm.blogspot.com/2011/09/diy-time-lapse-dolly.html
What are you using as a controller?

@musicforpeople - The controls for the camera are self contained. To control the speed of the dolly I either changed the size of the pully or for finer control I adjusted the potentiometer.

The camera was a GoPro Hero which has a built in invertalometer.
