Hi Oseegee,

I have a friend named Chris who's a Jeweller doing CAD/CAM & is very good with Rhino.
In the last 12mths he's also taught himself how to model "organic" style pieces using the Rhino Plug-in called T-Splines.
One model that he was asked to create, was a Dragon pendant.

He made a video at the time to help others understand how he went about creating that particular model using T-Splines.
Here's a link:
