Why animated?: There are some beards around here, that do not follow facial expressions. So when your Avi smiles, his (or her :-)) moustache stays where it is and covers your mouth. A animated beard moves with all standard facial expressions. It looks great no matter if you smile, laugh, frown or scream.
Since every head has a different chin shape, the beard will look slightly different. I tried to make it match every head and avoid gaps. However, I could not test every single head out there, so please try before you buy!
There is a derivable version too...
