So here's an unexpected twist.  I was working on yet another variation of Gemini, and I neglected to clear out one of my content folders before creating the figure, that folder or library contained the MetaMixer Toolkit.  Long story short, all those dials carried over to my Real Gemini, I also applied one of the dark skinned material presets, dialed in all the Neda dials and voila.  I'm sure they're not meant to be used that way, but what the heck,  it works for me.
