Flowing scales with texture in proportion

I have Rhino 5 & T-Splines 3. I’m interested in making FISH scales, or LIZARD or SNAKE scales on a model with a CURVE NETWORK so that the scales FLOW along the curves correctly in proportion to the model. There is a YouTube clip here that is a YEAR old and very long with poor audio. Anybody got anything that cuts to the chase? http://youtu.be/FSFPA8EcY1k
