You might have seen it over at OpenGameArt.org already, but we (well mostly I) are working on a rig for humanoid game characters, hopefully ending up with a really good rig and a big set of pre-made animations for all sort of games.
Have a look at the progress here:

And join the discussion here:

As you can probably tell, this is also a learning experience for me. So in other words I am very much looking for input from some one who actually knows what he is doing
Also once I declare the rig "final", it would be awesome if as many people as possible would start making cool animations with the rig.
