In reading through the Matmatic Extras, I see that you explain How you did the Marble and Wood.

Would it be possinlt to put together the Statements to use the 3D Nodes please?

I think if I new How to insert the Various Nodes Statements that i could certainly experiment away after that.

I tried substituting Granit, but got and err because I hadn't defined Granit

Cheers
