It is not a perpetual-motion machine, so someone will have to provide the rocking power. I chuckled while watching and listening to our granddaughters discuss who will be the first to rock their new baby in the cradle.
I am working on resolving a problem with the aspect ratio of the video. Once this is resolved, I will be able to post the actual video directly in this article. Meanwhile, you can view the video by clicking on the link above. Thanks for your patience!
