If you're serious about this animation of certain features, then I say instead of an animation for talking in party or say that the animation acts on certain key words. For instance......And I hate this word.......Certain things said in chat, such as, "lol" could be used to activate the character to laugh hysterically. "lmfaorofl" That'll be good.......Basically that should animate the character into a Homer Simpson dance on the floor.....Hahaha! Certain key structures such as that would be funny to watch no matter what.
