About this 3D model

It was my son's idea to create a dinosaur skull that would sing jingle bells. This is the result of that project. The bottom jaw is controlled via a servo mounted in the base. In this video you can see the skull in action singing jingle bells. http://youtu.be/Z-ojvIRqI_Q Undubbed with circuit board visible http://www.youtube.com/watch?v=0hoYsfMroyg
