A good supply of free motion capture (.bvh) is mocapdata. Also if you are in need of a no-nonsense audio editor try Audacity
I for one like the term ANYMATION which Overman has forwarded to the Antics Forum. original article I had heard the term used in dscussion here and there and I think it is closer to describing Antics clips than the Machinima label. I don't think it's the best name, I'm just not offended by it.
On another note, I had a little fun with my newly built skeleton dudes, now that's using your head! T. (btw, I did the sound also)
