That was coming. The c in z**2 + c ranges over a patch of the complex plane, with the colored dot measuring the convergence/divergence at that point. Fractals are a vehicle for understanding complex numbers in my book -- to avoid them is to miss an opportunity. http://www.4dsolutions.net/ocn/fractals.html I like that you're working from the prompt, interactively. > P.S. another fun and easy way to introduce fractals is with the "chaos > game". I also use Wolfram's stuff in Tk to introduce unpredictable complexity from simple (perhaps unknown) rules. Deja vu. Haven't we had this discussion before?
