My old officemate made a lab in which students developed a library for
this themselves. Actually the lab writeup was really fun, so you might
want to take a look at it:


It was called the "Fractal Homer" lab, for reasons that are probably
clear. The only real trick was that it's very useful to tell the
students to make an intermediate color-matrix (i.e. list of lists of
colors, where each list of colors has the same length) rather than
trying to figure out the definitions on flat color lists directly.
