Thanks for mentioning "Waveforms" didn't know about that.
Thinking about these function patterns is actually surprisingly fun. Managed to
make a polkadot pattern by a function f(x,y,z)-->[0,1] that I think I can use as
a basis for a good a starry sky texture with a lot of control on the appearance
of the stars. I will post pictures in the next few weeks hopefully when I have
more time.
