Wallace & Company are for certain geniuses... that fact aside, the use of automated body parts within grand illusions is a very expensive "extra" that really isn't practical for the most part.
When I was doing big illusions I thought this was important and had some amazing add-ons to certain props. The head to one of my pieces actually seemed to be chewing gum and even blew a nice pink bubble (part of a 50's act we were doing). I know of one designer that had an amazing set of legs, which allowed the leg/foot compartment of his vivisection effect, to walk off stage.
The reality to such things is that you are adding several thousand dollars to the expense of your effects systems when using this technology which, for most, isn't practical and in performance, it rarely makes that big of a difference in the mind of the audience.
Like everything in life there are exceptions to this rule; some of the newer "cutting edge" bits that are out there actually require this kind of technology so as to add to the cleanliness and deception of the effect, but this is in but a slim side of reality.
