PERL and Mandelbrot Fractals

Mandelbrot Fractal created on a single Raspberry Pi

As I continue to research parallel computing methods on the raspberry pi cluster, I have been investigating fractal generation, specifically Mandelbrot fractals.  In the process, I found an example PERL script that generated a Mandelbrot fractal.  I wish I had the original link, but I have lost it.  I have rewritten it several times over in an attempt to both understand and simplify the process before I attempt parallelizing it.  You will notice in the image above that I chose to add random colors to the interior instead of making it a solid color.  The current phase of the code can be found here.  I will be working on adding the parallel components to it this week and will add a post with the code when it has been completed.
