Yes, I have a pigment_map, mainly to convert the greyscale (well, scalar) values
of `cells` to some colors. Currently I have:

------
                color_map {
                        [0.00 color Red]
                        [0.17 color Yellow]
                        [0.33 color Green]
                        [0.50 color Cyan]
                        [0.66 color Blue]
                        [0.83 color Magenta]
                        [1.00 color Red]
                }
------

Problem though, is how to vary the color_map entries by `clock`?

P.S. Oh nevermind, just realized povray allows the color part of each entry to
be variable. So I could do something like Red + Green*clock, Green + Blue*clock,
etc., to get what I want.

Thanks for the idea!
