Here's a character rig I made for Animation III class. The assignment was to take any clip and do a little bit of lip-sync as well as movement to compliment it - using a character rig with Toon Boom's network system. I chose an Office Space Quote and a big slurp noise. This piece was featured in CCAD's 134th Annual End-of-the-Year Student Show.
