Just discovered that facerig have added Starbound 3D avatars to download for use:
Facerig on Steam: http://store.steampowered.com/app/274920/
"FaceRig is a program that aims to enable anyone with a webcam to digitally embody awesome characters. The output can be recorded as a movie or streamed to Skype, Twitch, Hangouts or any service that traditionally uses a webcam in real time."
You can basically use Facerig to use a 3D avatar that tracks your visual facial expressions via your webcam, you can play your games like Starbound while using FR to appear to people without showing your actual face (for those that want to use the custom avatars).
