NinjaLA is working on a posable Kilrathi model. He's still working on the textures and skeleton to manipulate, but the basic model shape is together. It seems like a pretty accurate representation, though I have to admit looking at it definitely creeps me out.
I think the legs are pretty broken at the moment, and I'll detail up the head a bit more. Right now I think it's around 200k polys so it's not exactly a game model. It would be nice in video format though.
