I'm a big Yoda fan myself. I have a much smaller scaled ESB Yoda sculpt going at the moment. With ages plunked into it.
One thing I've noticed about the ESB Yoda puppets eyes- is that there appears to be an optically clear vacuformed styrene shell that rest over the animatronic acrylic eyes.
I believe this was done to prevent frictional wear and tear from the animatronic eye moments against the latex lids. This also means that basically the eyes orbital form/shape is always the same shape even when the eyes move around underneath this clear protective casing.
I've yet to see anyone else detect or talk about this. I watched chapter 31's Yoda's "Feel the Force" speech for several hours in HD resolution from a ripped VOB too come too this conclusion- as I was having eye issues with my sculpt.
I'm nearly 99.9 percent sure about this now.
