I must admit, that I have never used this, neither can I find a graphical
example of what it looks like.

I'm also presuming that it's different from the cubic pigment pattern

Given the fact that I've been investigating and experimenting more with
functions and patterns, this also makes me wonder how hard it would be to make a
superellipsoid warp.

Based upon a cursory reading of this (pg 19):

It seems to me that perhaps a modification of the spherical warp might be the
way to go?
