Kip,

My thoughts.

Use the siccsor jack principle to raise the head.
Offset the weight with rubber bands or surgical 
tubing or small springs - between each wide
space in the springs

Keep mass low; Head big inflatable head or baloon
made to look like a head.

Use fabric for neck.

Use fast cable wench to raise and lower
