So, this is what all that lattice work was in aid of.

It's still not quite there yet. I dummied up the height because I haven't moved the furniture node yet, and the connections aren't precise, but that'll go away when I add the socket caps.

Really though, it couldn't work much better. The frame is study, the connections are in a line with the arm and leg bones

And of course, she's at just the right height for sex. I'm thinking maybe the male half of Crazy's standing animation. That was designed with a static female partner, so it should work quite well.

If I can make all that work, the next thing to do is look at connection points. I'd like to take the upper portion of that frame and stack it vertically, maybe see how densely I could pack the inhabitants. And if I can make it work, maybe set up an elevator platform for the male; one that would take you up in small increments, just enough to put you at the right level to have sex with the girls higher up in the frame.
