Thanks for that node clip, there, ice-boy. Had me a bit of fun with it. First of all, I have NO blessed idea what I'm doing. I'm attempting to leverage what I think I know about shaders in building this one. Probably my first mistake, since my knowledge is still on pretty shaky pilings.

Anyway, here's the code:

  addNaught = Add(0, 0)
  hairTxtr = FractalSum(
    .000004 * u_Texture_Coordinate(),
    4 * addNaught, 
    4 * addNaught, 
    8, 
    .3, 
    .5, 
    .5).labelled("FractalSum")

  setSpecular = Anisotropic(
    hairTxtr, 
    4, 
    .5, 
    .22, 
    0, 
    1, 
    0).labelled("Anisotropic")

Not exactly your original numbers. Here's the shader in a form you're more familiar with:

...and the hair file I cobbled together quickly in the GIMP to use with Tequila Hair:

..and a piccie:

Not sure if the weird artifacts in the hair is due to the poor colourMap or if I need to muck around with the shader. Still have a long way to go with this one... but thanks for the clues, BB. Probably totally mis-using them and everything, but I'm having a great time doing it!
