"NewtonMap-Algebraic" by Huangxin Wang, Univ. of Pennsylvania

"NewtonMap" runs on any color Macintosh.  It displays the basins of attraction for the Newton's iterative method for solving the single-complex-variable equation:

  z <- z - f(z) / f'(z),  in this module, f(z) is an algebraic function.

Since it takes a long time to finish a complete map, it always resumes from where it stops last time.  You can delete the "NewtonMap.resume" file to have a fresh start.

You should turn off "SystemIQ" in AfterDark for better speed.
