No reverse skeleton. Just a chain with a few connections and nodes and expressions ;) I haven't seen the Ryan rig. I just saw some of the render stuff last year during SIGGRAPH. Very impressive. Hopefuly I will also be winning an Oscar one of these years. I will be the first salvadorean to win one ;) Anyway, I will work on that tut about the arm and I will post it in the Maya forum so everybody else can see it too.
