Alright, this'll be the last one of the damned dragon for awhile, I swear.
This thing has an articulated jaw (physically moves, not just using the full alpha toggle many use), and several funky eye expressions. It was missing one that I thought should be included, but I didn't realize it until a few weeks ago. It's so close to being released that it would be stupid to put in a feature request.
I added a small script to the head that listens alongside the main expression control script (which is blackboxed), and just toggles the eye texture between the one I made and the default. The interesting thing is that I had to specially set my add-on script to toggle the awesomeface eyes AND the default eye texture, since for some reason the stock controller won't change it back, and treats it like the default.

Better than Legos.
Well, it's pretty close, anyway.
