I've been looking for an appropriate condensor microphone to put inside my fursuit's mouth so I can do video recordings without sounding muffled. The idea of voice-over seems like cheating to me. But, that's me.

As to the articulated jaw...I don't know if you made your costume, but if you did or plan to, the articulated jaw is quite easy to engineer. Your own jaw joint pivots just below your ear (you can feel this.) You then simply create a jaw of the same shape as your jaw bone (look at a skeleton or picture thereof to get an idea of the shape of your jawbone) and run it down parallel to your own, then simply connect the muzzle to it, and presto, perfectly articulated jaw. The other trick is balancing the spring/elastic (I made mine adjustable) and the padding for your jaw. You'll have to always shave or at least trim your beard down to where it was when you made the mechanism; but it's well worth it.

Check mine out: http://www.furaffinity.net/journal/7819532/ (video embedded, I hope.)

I'll see if I can find my photos and photoshop masks wherein I designed my latest articulated jaw. If I can, I'll try to post them and link you to them, if you'd like.

A fox that cheats? Never! Sir, you have offended me. :P

Mixed Candy made my fursuit. I make fursuits as well, but mine are toony, using the balaclava and foam method.

Sure! Go for it! :)

A most inspiring video!

Thanks, Captain. I try. :)

No, you do not try - you DO. ;)
