It was at rendervisions but it looks like they've had a meltdown.  I'll post a diagram tomorrow night.  Right now I'm drawing up a new lightwave rigging,  hopefully I'll be able to use it in Poser as well.  It involves kind of a pendulum attached to the thigh bone. One running on the z axis and one running on the x axis.  I'm trying to get a sway in the glutes and jiggle in the thighs.
