And I think you just answered why we have not seen those items yet. To hard to get working in all the shapes possible.
Not knowing the mechanics of how Genesis is created, data-wise, I’m unsure if this would work, but couldn’t it effectively be a slightly altered version of the Genesis figure, itself? Strategic transparencies and all? At least, for the skeleton… The muscular frame could be done with a different type of skin (or at least, that’s how I’ve seen it done in Second Life - the visual effect’s plausible enough). Organs, yeah… I can see them being very different.
I could see a ‘proper’ Genesis skeleton having some intriguing new morphing possibilities, though. Things like giving or removing emphasis from certain bones, like the vertebrae, to give an appearance of spikes/talons/etcetera.
They should work with all the Genesis shapes.
For conventional adult shapes, I can believe, but does it conform in the same way for, say, overweight body shapes, where the rib structure would be different? Or the kind of heights you can get with Genesis, where it can be anything from two to eight feet in height?
I’d also imagine adult and child bone structures might have some differences, but it’s been a while since I’ve had to study human biology.
