I'm wrapped by my own words but I cannot give up in try to make a complete head turn with this giraffe.
Please watch the WIP work to do a head turn.

it was only done by point motion so there is no interest in the anme file. It is like a preparation to make it a 3D rig using heyvern's script what converts two bones rotation into a 3D point rotation. I hope that the 3D rig improve the displacement velocity of the points. Now the left side of the face is a little slow compared to the right part. it makes the frames before the 3/4 view a little strange.
There are some missing shapes and there are no eyes and ears for the moment.
Just WIP.

Thanks
