Hi

- I've been working on some some macros that create functions for calculating
with complex numbers.

And yesterday I made some functions that can be used for HSV-coloring of
pigments.

The isosurface in the attached image shows the magnitude (or modulus) of this
function:

  Fn(Z) = 1/(Z^5 - 2)^2

- as the height above a complex plane:. I found that function here:

The colors are chosen so that the hue follows the phase (or argument) of the
function, while the lightness goes from 0.0 to 0.5 in intervals along the height
axis. The saturation is 100% everywhere.
